18.2 Dynamic PWM
There are two dynamic PWMs in the HMS9xC7134. The DP-
WMs can be used to generate various waveform by software pro-
gramming, and are used to achieve geometric compensation by
generating a parabola output waveform which is synchronized
with VSYNCin signal for pin/trap, bow/tilt, vertical linearity or
focus compensation in monitor system.
This is achieved by utilizing timer2. The low 8-bit in timer2 is
used as 8-bit counter for PWM signal and the high 8-bit in timer2
is used to decide the number of PWMs in one video frame. One
video frame can be divided to any number of blocks according to
the register RC2H value within 256 blocks, and here the RC2L
will be 00H for 8-bit PWM resolution.
The dynamic PWM outputs DPWM0 to DPWM1 register share
the same pins as Port2.0~Port2.1respectively.
The repetition frequency (fDPWM) at a DPWM output is given
by (in case of RC2L=00H): fDPWM = fOSC / (2 x 256)
