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 441).
If this register is re-written before the actual update occurs, the previous value is never used and is
lost.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Counter Load Value
The counter load value.
