Bit Position Bit Name
63 to 0 SYSTIME
Remarks 1. Bits 63to 8 are internally latched (ECAT/PDI independently) when bits 7 to 0 are read, which
guarantees reading a consistent value.
2. Clearing the Latch0 status flag function depends on the setting of bit 4 in the cyclic unit
control register (DC_CYC_CONT: 0x0980).

These bits indicate the system time captured at the negative edge of Latch0 input signal.
Reading this register clears bit 1 in the Latch0 status register (DC_LATCH0_STAT:
0x09AE).
