PPS0 Target Time Nanoseconds Register
TTSL0 | Target Time Low for PPS Register This register stores the time in (signed) nanoseconds. When the value of the timestamp matches the value in both ETH_MAC_PPS0_TARGET_TIME_SECONDS and ETH_MAC_PPS0_TARGET_TIME_NANOSECONDS registers, the MAC generates an interrupt (if enabled). When the ETH_MAC_TIMESTAMP_CONTROL[TSCTRLSSR] bit is reset, this value should be (time in ns / 0.465). When the ETH_MAC_TIMESTAMP_CONTROL[TSCTRLSSR] bit is set, this value should not exceed 0x3B9A_C9FF. Access restriction applies. Setting 1 sets. Self-cleared. Setting 0 has no effect. |
