Register 24: PWM0 Load (PWM0LOAD), offset 0x050
Register 25: PWM1 Load (PWM1LOAD), offset 0x090
Register 26: PWM2 Load (PWM2LOAD), offset 0x0D0
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 configured by the MODE bit in the
PWMnCTL register, this value is either loaded into the counter after it reaches zero or is the limit
of up-counting after which the counter decrements back to zero. When this value matches the
counter, a pulse is output which can be configured to drive the generation of the pwmA and/or pwmB
signal (via the PWMnGENA/PWMnGENB register) or drive an interruptor ADC trigger (via the
PWMnINTEN register).
If the Load Value Update mode is locally synchronized (based on the LOADUPD field encoding in
the PWMnCTL register), the 16-bit LOAD value is used the next time the counter reaches zero. If
the update mode is globally synchronized, 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 842). If this register is re-written before the actual update occurs, the previous value is
never used and is lost.

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.
