8.4.1 PMD0

PMD Control Register 0
Note:
  1. Clearing the SYSCMD bit disables the system clock (FOSC) to peripherals, however peripherals clocked by FOSC/4 are not affected.
  2. Subject to SCANE bit in Configuration Word 4.
  3. When enabling NVM, a delay of up to 1 µs is required before accessing data.
