Register 18: PWM0 Load (PWM0LOAD), offset 0x050
Register 19: PWM1 Load (PWM1LOAD), offset 0x090
These registers contain the load value for the PWM counter (PWM0LOAD controls the PWM
generator 0 block, and so on). Based on the counter mode, either this value is loaded into the
counter after it reaches zero, or it is the limit of up-counting after which the counter decrements
back to zero. If the Load Value Update mode is immediate, this value is used the next time the
counter reaches zero; if the mode is synchronous, it is used the next time the counter reaches zero
after a synchronous update has been requested through the PWM Master Control (PWMCTL)
register (see page 363). If this register is re-written before the actual update occurs, the previous
value is never used and is lost.
