Comparator Inputs.
Two analog comparators are added
to input of Port 3, P31, and P32, for interface flexibility. The
comparators reference voltage P33 (REF) is common to
both comparators.
Typical applications for the on-board comparators; Zero
crossing detection, A/D conversion, voltage scaling, and
threshold detection. In Analog Mode, P33 input functions
serve as a reference voltage to the comparators.
The dual comparator (common inverting terminal) features
a single power supply which discontinues power in STOP
Mode. The common voltage range is 0-4 V when the V
CC
is 5.0V; the power supply and common mode rejection ra-
tios are 90 dB and 60 dB, respectively.
Interrupts are generated on either edge of Comparator 2's
output, or on the falling edge of Comparator 1's output.
The comparator output is used for interrupt generation,
Port 3 data inputs, or T
IN
through P31. Alternatively, the
comparators can be disabled, freeing the reference input
(P33) for use as IRQ1 and/or P33 input.
FUNCTIONAL DESCRIPTION
The following special functions have been incorporated
into the Z86E04/E08 devices to enhance the standard Z8
core architecture to provide the user with increased design
flexibility.
RESET
. This function is accomplished by means of a Pow-
er-On Reset or a Watch-Dog Timer Reset. Upon power-
up, the Power-On Reset circuit waits for T
POR
ms, plus 18
clock cycles, then starts program execution at address
000C (Hex) (Figure 10). The Z86E04/E08 control registers'
reset value is shown in Table 3.
Power-On Reset (POR).
A timer circuit clocked by a ded-
icated on-board RC oscillator is used for a POR timer func-
tion. The POR time allows V
CC
and the oscillator circuit to
stabilize before instruction execution begins. The POR
timer circuit is a one-shot timer triggered by one of the four
following conditions:
I
Power-bad to power-good status
I
Stop-Mode Recovery
I
WDT time-out
I
WDH time-out
Watch-Dog Timer Reset.
The WDT is a retriggerable
one-shot timer that resets the Z8 if it reaches its terminal
count. The WDT is initially enabled by executing the WDT
instruction and is retriggered on subsequent execution of
the WDT instruction. The timer circuit is driven by an on-
board RC oscillator.
