PWMOUT:
This instruction is used to transfer the contents of
register A and register B to only reload register R1.
PWM output signal (from timer 4 output unit)
Data is set automatically from each reload
register when timer underflows
(auto-reload function).
Notes 1: When CMCK instruction is executed, ceramic resonance is selected.
When CRCK instruction is executed, RC oscillation is selected.
When CYCK instruction is executed, quartz-crystal oscillator is selected.
2: Timer 1 count start synchronous circuit is set by the valid edge of P30/INT0 pin
selected by bits 1 (I11) and 2 (I12) of register I1.
3: XIN cannot be used for the count source when bit 1 (MR1) of register MR is set
to “1” and f(XIN) oscillation is stopped.
