Interrupts
Starting Ping-Pong Mode
First, make sure both counter/timers are not running. Then set T8 into Single-
Pass Mode (CTR0 D6), set T16 into Single-Pass Mode (CTR2 D6), and set Ping-
Pong Mode (CTR1 D2, D3). These instructions do not have to be in any particular
order. Finally, start Ping-Pong Mode by enabling either T8 (CTR0 D7) or T16
(CTR2 D7).
During Ping-Pong Mode
The enable bits of T8 and T16 (CTR0 D7, CTR2 D7) are alternately set and
cleared by hardware. The time-out bits (CTR0 D5, CTR2 D5) are set every time
the counter/timers reach the terminal count.

The Z86E7X has five different interrupts. The interrupts are maskable and priori-
tized, as shown in
