System Control
Register 37: Pulse Width Modulator Peripheral Present (PPPWM), offset 0x340
The PPPWM register provides software information regarding the PWM modules.
Important: This register should be used to determine which PWM modules are implemented on
this microcontroller. However, to support legacy software, the DC1 register is available.
A read of the DC1 register correctly identifies if the legacy PWM module is present.
Software must use this register to determine if a module that is not supported by the
DC1 register is present.

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.
