Pwm Output Operation (Output With 1 Clock Shifted) - NEC mPD780973 Series Preliminary User's Manual

18.4.4 PWM output operation (output with 1 clock shifted)

Count clock
Meter 1 sin
(SM11, SM12)
Meter 1 cos
(SM13, SM14)
Meter 2 sin
(SM21, SM22)
Meter 2 cos
(SM23, SM24)
Meter 3 sin
(SM31, SM32)
Meter 3 cos
(SM33, SM34)
Meter 4 sin
(SM41, SM42)
Meter 4 cos
(SM43, SM44)
If the wave of sin and cos of meters 1 to 4 rises and falls internally as indicated by the broken line, the SM11
to SM44 pins always shift the count clock by 1 clock and output signals, in order to prevent V
