ranges from 0000h to the value stored in the 16-bit cap-
ture/reload register (TBR), whereas in other implemen-
tations (e.g., Timer 1) the count ranges from the value
in the reload register to FFFFh. These timers are fully
described in the
MAXQ Family User’s Guide.
Timer B operational modes include the following:
Autoreload
Autoreload Using External Pin
Capture Using External Pin
Up/Down Count Using External Pin
Up-Count PWM/Output
Up/Down PWM/Output
Clock Output on TBB Pin
Watchdog Timer
An internal watchdog timer greatly increases system reli-
ability. The timer resets the device if software execution
is disturbed. The watchdog timer is a free-running
counter designed to be periodically reset by the applica-
tion software. If software is operating correctly, the
counter is periodically reset and never reaches its maxi-
mum count. However, if software operation is interrupted,
the timer does not reset, triggering a system reset and
optionally a watchdog timer interrupt. This protects the
system against electrical noise or electrostatic discharge
(ESD) upsets that could cause uncontrolled processor
operation. The internal watchdog timer is an upgrade to
older designs with external watchdog devices, reducing
system cost and simultaneously increasing reliability.
The watchdog timer is controlled through bits in the
WDCN register. Its timeout period can be set to one of
four programmable intervals ranging from 212 to 221
system clocks in its default mode, allowing flexibility to
support different types of applications. The interrupt
occurs 512 system clocks before the reset, allowing the
system to execute an interrupt and place the system in
a known, safe state before the device performs a total
system reset. At 8MHz, watchdog timeout periods can
be programmed from 512s to 67s, depending on the
system clock mode.
Hardware Multiplier
The internal hardware multiplier supports high-speed
multiplications. The multiplier can complete a 16-bit x
16-bit multiply-and-accumulate/subtract operation in a
single cycle with the support of a 48-bit accumulator.
The multiplier is a fixed-point arithmetic unit. The
operands can be either signed or unsigned numbers,
but the data type must be defined by the application
software prior to loading the operand registers.
Seven different multiply operations can be performed
without requiring direct intervention of the microcon-
troller core. These include the following:
Unsigned 16-bit multiplication
Unsigned 16-bit multiplication and accumulation
Unsigned 16-bit multiplication and subtraction
Signed 16-bit multiplication
Signed 16-bit multiplication and negate
Signed 16-bit multiplication and accumulation
Signed 16-bit multiplication and subtraction
Each of these operations is controlled and accessed
through six SFR registers. The 8-bit multiplier control
register (MCNT) selects the operation, data type,
operand count, optional hardware-based square func-
tion, write option on the MC register, the overflow flag,
and the clear control for operand registers and accu-
mulator. Loading and unloading of the data is achieved
through five 16-bit SFR registers.
Only one cycle is needed for computation. This means
that the result of an operation is ready in the next cycle
immediately following the loading of the last operand.
Back-to-back operations can be performed without wait
states between operations, independent of data type
and operand count.
Analog-to-Digital Converter
The MAXQ2010 contains a 12-bit successive approxi-
mation analog-to-digital converter (ADC) with an analog
mux (Figure 7). The mux selects the ADC input from
eight single-ended channels or four differential chan-
nels. An internal precision bandgap reference can be
used for the ADC reference voltage, or the reference
voltage can be externally driven. Additionally, the ana-
log supply voltage (AVDD) can also be used as the
voltage reference. The ADC runs off a 2.7V to 3.6V
power supply and at a conversion rate up to 300ksps.
The ADC block includes a 12-bit SAR core, ADC con-
trols, a reference generator, and a circular block of six-
teen 12-bit data buffers. The ADC is controlled by SFR
registers. An autoscan feature allows the user to select
up to eight sampling channels for storage in the 16
memory locations.
There are two conversion modes: single-sequence
mode and continuous-sequence mode.
The ADC’s internal power-management system auto-
matically powers down when the conversion(s) are
done (ADCONV = 0). The start conversion bit,
ADCONV, is used to start all conversion processes. If
the ADC power-management override bit is cleared
