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 can be in random order. Finally, start PING-
PONG mode by enabling either T8 (CTR0, D7) or T16 (CTR2, D7), see
The initial value of T8 or T16 must not be
reload the initial value to avoid an unknown previous value.
During PING-PONG Mode
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by
hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers
reach the terminal count.
Timer Output
The output logic for the timers is displayed in
when D0 of CTR0 is set. P35 is used to output the value of TI6-OUT when D0 of CTR2 is
set. When D6 of CTR1 is set, P36 outputs the logic combination of T8-OUT and T16-
OUT determined by D5 and D4 of CTR1.
The Crimzon ZLP32300 features six different interrupts (see
interrupts are maskable and prioritized (see
