During Ping-Pong Mode
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alter-
nately by hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the
counter/timers reach the terminal count.
Interrupts
The Z86D73 feature six different interrupts (Table 15). The interrupts are
maskable and prioritized (Figure 31). The six sources are divided as follows: three
sources are claimed by Port 3 lines P33–P31 and two by the counter/timers
(Table 15). The Interrupt Mask Register (globally or individually) enables or dis-
ables the five interrupt requests.
