Pulse Width Modulator (PWM)
Register 14: PWM0 Load (PWM0LOAD), offset 0x050
contain the load value for the PWM counter. 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 325). If this register is re-written before the actual update occurs,
the previous value is never used and is lost.
