NPC_PCR[FPM] = 0

NPC_PCR[NEXCFG] = 0

The Nexus AUX port runs up to 40 MHz. Set NPC_PCR[MCKO_DIV] to divide-by-two if the system frequency is greater

than 40 MHz.

NPC_PCR[FPM] = 1

Set the NPC_PCR[MCKO_DIV] to divide by two if the system frequency is between 40 MHz and 80 MHz inclusive. Set the

NPC_PCR[MCKO_DIV] to divide by four if the system frequency is greater than 80 MHz.

Pad restrictions limit the Maximum Operation Frequency in these configurations

NPC_PCR[NEXCFG] = 1
