Revision A1
The Timer 1 starts to count when the STTM1 REG. bit3 is set. When Timer 1 overflows, the STTM0
bit3 will be reset by hardware to stop Timer 1 if the auto-reload is disabled, but the STTM1 bit3 will
not be reset if the auto-reload is enabled.
When the Timer 1 function is performed, the special function will be disabled automatically. The
special function input or output is from or to P5.0.
The format of the Timer 1 event counter condition is shown as follows
TGTM1 REG: (ADDRESS = 029H)
(Default data = 0H)
b3
b2
b1
b0
0: Event counter is falling edge trigger
1: Event counter is rising edge trigger
0: Special function work as event counter
1: Special function work as arbitrary
waveform generator
0: Arbitrary waveform type 0
1: Arbitrary waveform type 1
