Initiating Ping-Pong Mode
First, make sure both counter/timers are not running. Set T8 into Single-Pass
Mode (CTR0, D6), set T16 into Single-Pass Mode (CTR2, D6), and set the 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). See Figure 30.
