To Initiate Ping-Pong Mode
First, make sure both counter/timers are not running. Then
set T8 into Single-Pass Mode (CTR0 D6), set T16 into Sin-
gle-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 en-
abling either T8 (CTR0 D7) or T16 (CTR2 D7).

During Ping-Pong Mode
The enable bits of T8 and T16 (CTR0 D7, CTR2 D7) will
alternately be set and cleared by hardware. The time-out
bits (CTR0 D5, CTR2 D5) will be set every time the
counter/timers reach the terminal count.
