Description

PPS control register

Fields

PPSCTRL

PPS Output Frequency Control

1 (B_0x1): The binary rollover is 2 Hz, and the digital rollover is 1 Hz.

2 (B_0x2): The binary rollover is 4 Hz, and the digital rollover is 2 Hz.

3 (B_0x3): The binary rollover is 8 Hz, and the digital rollover is 4 Hz.

4 (B_0x4): The binary rollover is 16 Hz, and the digital rollover is 8 Hz.

15 (B_0xF): The binary rollover is 32.768 KHz and the digital rollover is 16.384 KHz.

PPSEN0

Flexible PPS Output Mode Enable

TRGTMODSEL0

Target Time Register Mode for PPS Output

0 (B_0x0): Target Time registers are programmed only for generating the interrupt event.

1 (B_0x1): Enables MCGR Interrupt whose status bit is indicated by TSTARGT0 bit in Timestamp status register (ETH_MACTSSR) register

2 (B_0x2): Target Time registers are programmed for generating the interrupt event and starting or stopping the PPS output signal generation.

3 (B_0x3): Target Time registers are programmed only for starting or stopping the PPS output signal generation. No interrupt is asserted.

MCGREN0

MCGR Mode Enable for PPS0 Output

0 (B_0x0): PPS mode

1 (B_0x1): MCGR mode

TIMESEL

Time Select
