X96012
PRINCIPLES OF OPERATION
CONTROL AND STATUS REGISTERS
The Control and Status Registers provide the user with
a mechanism for changing and reading the value of
various parameters of the X96012. The X96012 con-
tains seven Control, one Status, and several Reserved
registers, each being one Byte wide (See Figure 4).
The Control registers 0 through 6 are located at mem-
ory addresses 80h through 86h respectively. The Sta-
tus register is at memory address 87h, and the
Reserved registers at memory address 88h through
8Fh.
All bits in Control register 6 always power up to the
logic state “0”. All bits in Control registers 0 through 5
power up to the logic state value kept in their corre-
sponding nonvolatile memory cells. The nonvolatile bits
of a register retain their stored values even when the
X96012 is powered down, then powered back up. The
nonvolatile bits in Control 0 through Control 5 registers
are all preprogrammed to the logic state “0” at the fac-
tory.
Bits indicated as “Reserved” are ignored when read,
and must be written as “0”, if any Write operation is
performed to their registers.
A detailed description of the function of each of the
Control and Status register bits follows:
Control Register 0
This register is accessed by performing a Read or
Write operation to address 80h of memory.

These two bits are used to inhibit any write operation to
certain addresses within the memory array. The pro-
tected region of memory is determined by the values of
the two bits as shown in the table below:
If the user attempts to perform a write operation to a
protected region of memory, the operation is aborted
without changing any data in the array.
Notice that if the Write Protect (WP) input pin of the
X96012 is active (LOW), then any write operation to
the memory is inhibited, irrespective of the Block Lock
bit settings.

The VRM bit configures the Voltage Reference pin
(VRef) as either an input or an output. When the VRM
bit is set to “0” (default), the voltage at pin VRef is an
output from the X96012’s internal voltage reference.
When the VRM bit is set to “1”, the voltage reference
for the VRef pin is external. See Figure 5.

The ADCIN bit selects the input of the on-chip A/D con-
verter. When the ADCIN bit is set to “0” (default), the
output of the on-chip temperature sensor is the input to
the A/D converter. When the ADCIN bit is set to “1”, the
input to the A/D converter is the voltage at the VSense
pin. See Figure 7.

When this bit is“1”, the status register at 87h is updated
after every conversion of the ADC. When this bit is “0”
(default), the status register is updated after four con-
secutive conversions with the same result, on the 6
MSBs.

When the NV1234 bit is set to “0” (default), bytes writ-
ten to Control registers 1, 2, 3, and 4 are stored in vola-
tile cells, and their content is lost when the X96012 is
powered down. When the NV1234 bit is set to “1”,
bytes written to Control registers 1, 2, 3, and 4 are
stored in both volatile and nonvolatile cells, and their
value doesn’t change when the X96012 is powered
down and powered back up. See “Writing to Control
Registers” on page 24.

The I1DS bit sets the polarity of Current Generator 1,
DAC1. When this bit is set to “0” (default), the Current
Generator 1 of the X96012 is configured as a Current
Source. Current Generator 1 is configured as a Current
Sink when the I1DS bit is set to “1”. See Figure 8.
