During PING-PONG Mode
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by
hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers
reach the terminal count.
Interrupts
The ZGP323H features six different interrupts
(Table
11). The interrupts are maskable and
prioritized
(Figure
28). The six sources are divided as follows: three sources are claimed
by Port 3 lines P33–P31, two by the counter/timers
(Table
11) and one for low-voltage
detection. The Interrupt Mask Register (globally or individually) enables or disables the
six interrupt requests.
The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M). When in
digital mode, Pin P33 is the source. When in analog mode the output of the Stop Mode
Recovery source logic is used as the source for the interrupt. See
Figure
33, Stop Mode
Recovery Source, on page 53.
