1.4.7 PD5 and PD7/TCAP
These two I/O pins comprise port D and one of them is shared with the
16-bit timer subsystem. The state of PD5 is software programmable and
is configured as an input during power-on or reset. PD7 is always an
input. It may be read at any time, regardless of which mode of operation
the 16-bit timer is in. Refer to
Section 6. Input/Output Ports
and
Section 8. Capture/Compare Timer
.
1.4.8 TCMP
This pin is the output from the 16-bit timer
’
s output compare function. It
is low after reset. Refer to
Section 8. Capture/Compare Timer
.
1.4.9 IRQ/V
PP
(Maskable Interrupt Request)
This input pin drives the asynchronous interrupt function of the MCU in
user mode and provides the V
PP
programming voltage in bootloader
mode. The MCU will complete the current instruction being executed
before it responds to the IRQ interrupt request. When the IRQ/V
PP
pin is
driven low, the event is latched internally to signify an interrupt has been
requested. When the MCU completes its current instruction, the interrupt
latch is tested. If the interrupt latch is set and the interrupt mask bit (I bit)
in the condition code register is clear, the MCU will begin the interrupt
sequence.
Depending on the MOR LEVEL bit, the IRQ/V
PP
pin will trigger an
interrupt on either a negative edge at the IRQ/V
PP
pin and/or while the
IRQ/V
PP
pin is held in the low state. In either case, the IRQ/V
PP
pin must
be held low for at least one t
ILIH
time period. If the edge- and level-
sensitive mode is selected (LEVEL bit set), the IRQ/V
PP
input pin
requires an external resistor connected to V
DD
for wired-OR operation.
If the IRQ/V
PP
pin is not used, it must be tied to the V
DD
supply. The
IRQ/V
PP
pin input circuitry contains an internal Schmitt trigger to improve
noise immunity. Refer to
Section 5. Interrupts
.
NOTE:
If the voltage level applied to the IRQ/V
PP
pin exceeds V
DD
, it may affect
the MCU
’
s mode of operation. See
Section 3. Operating Modes
