26.6.2.2 Port Configuration Register (PCR)
The PCR is used to select the NPC mode of operation, enable MCKO and select the MCKO frequency,
and enable or disable MCKO gating. This register should be configured as soon as the NDI is enabled.
The PCR register may be rewritten by the debug tool subsequent to the enabling of the NPC for low-power
debug support. In this case, the debug tool may set and clear the LP_DBG_EN, SLEEP_SYNC, and
STOP_SYNC bits, but must preserve the original state of the remaining bits in the register.
NOTE
The mode or clock division must not be modified after MCKO has been
enabled. Changing the mode or clock division while MCKO is enabled can
produce unpredictable results.
