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 Z86L81/86/98 features six different interrupts (Table 14). The interrupts are
maskable and prioritized (Figure 26). The six sources are divided as follows: three
sources are claimed by Port 3 lines P33–P31, two by the counter/timers, and one
by LVD (Table 14). The Interrupt Mask Register globally or individually enables or
disables the six interrupt requests.
