I am using LPC932 with internal RC osc. to implement 4 channel PWMs under Asymm mode.
But I do now know how to adjust the duty cycle
of each PWM channel.

Current CCU reload values as below:
TOR2H = 0x00;
TOR2L = 0xFF;

Is it enough to adjust
[OCRAH:OCRAL], [OCRBH:OCRBL],
[OCRCH:OCRCL], [OCRDH:OCRDL],
directly ?

[ORCxH:ORCxL] reasonable range is 0x0000 to 0x00FF (0%
to 100%) Right ?
