Table 20-24. PPSCTRL Bit Field Values (continued)
DescriptionValue
When the PPSEN0 bit = 0x1, cancel START. This command cancels the START single pulse and
START pulse train commands if the system time has not crossed the programmed start time.
When thePPSEN0 bit = 0x0, the binary rollover is 16 Hz, and the digital rollover is 8 Hz.0x4
When the PPSEN0 bit = 0x1, STOP pulse train at time. This command stops the train of puses
initiated by the START pulse train command after the time programmed in the Ethernet MAC
Target Time Second/Nanoseconds (EMACTARGX) registers (MAC offsets 0x71C and 0x720).
When thePPSEN0 bit = 0x0, the binary rollover is 32 Hz, and the digital rollover is 16 Hz.0x5
When the PPSEN0 bit = 0x1, STOP pulse train immediately. This command immediately stops the
train of pulses initiated by the START pulse train command.
When thePPSEN0 bit = 0x0, the binary rollover is 64 Hz, and the digital rollover is 32 Hz.0x6
When the PPSEN0 bit = 0x1, cancel STOP pulse train. This command cancels the STOP pulse
train at the time command if the programmed stop time has not elapsed. The EN0PPS pulse train
becomes free-running on the successful execution of this command.
When thePPSEN0 bit = 0x0, the binary rollover is 128 Hz, and the digital rollover is 64 Hz.0x7
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 256 Hz, and the digital rollover is 128 Hz.0x8
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 512 Hz, and the digital rollover is 256 Hz.0x9
When the PPSEN0 bit = 0x1, this encoding is reserved.
When the PPSEN0 bit = 0x0, the binary rollover is 1.024 kHz, and the digital rollover is 512 Hz.0xA
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 2.048 kHz, and the digital rollover is 1.024 kHz.0xB
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 4.096 kHz, and the digital rollover is 2.048 kHz.0xC
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 8.192 kHz, and the digital rollover is 4.096 kHz.0xD
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 16.384 kHz, and the digital rollover is 8.092 kHz.0xE
When the PPSEN0 bit = 0x1, this encoding is reserved.
When thePPSEN0 bit = 0x0, the binary rollover is 32.768 KHz, and the digital rollover is 16.384
KHz.
0xF
When the PPSEN0 bit = 0x1, this encoding is reserved.
