Figure 29. Ping-Pong Mode
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.
Figure 30. Output Circuit
The initial value of T8 or T16 must not be
timer again, reload the initial value to avoid an unknown previous value.
