NOTES:
EXT PIN (PAI)
PWMCNT[7:0]
1. PHI1 HAS THE SAME FREQUENCY AS THE SYSTEM CLOCK; HOWEVER, IT DOES NOT HAVE THE SAME TIMING.
2. TCNT COUNTS AS A RESULT OF PHI1/4; PACNT COUNTS WHEN TCNT OVERFLOWS FROM $FFFF TO $0000 AND THE CONDITIONED
PAI SIGNAL IS ASSERTED.

1. PHI1 IS THE SAME FREQUENCY AS THE SYSTEM CLOCK; HOWEVER, IT DOES NOT HAVE THE SAME TIMING.
2. WHEN THE COUNTER ROLLS OVER FROM $FF TO $00, THE PWM PIN IS SET TO LOGIC LEVEL ONE.
PHI1
WHEN THE COUNTER EQUALS THE PWM REGISTER, THE PWM PIN IS CLEARED TO A LOGIC LEVEL ZERO.
