DATA5 3Dh/7Dh
Name
Register Description (DATA5: Clock master ID and NST resolution)
CMID3 - 0
NSTPRE2 - 0
The above data are for 20 MHz input.
(For 40 MHz input they are half; for 10 MHz input they double)
Adrs.
Bit 7
These bits define the clock master ID in the range of 1 to 15 (CMID4 is fixed to 0)
CMID3: MSB; CMID0: LSB
PSSL = Low causes CMID3 = 0.
Default: CMID3 - 0 = 0000 (Asynchronous to NST: free running)
If a non-zero value is set in bits CMID3 – 0, the synchronization to NST begins when a
packet is received from the next CMID.
These bits define the NST resolution (default: NSTPRE2 - 0 = 000)
000: 1.6 μs
001: 3.2 μs
010: 6.4 μs
011: 12.8 μs
100: 25.6 μs
101: 51.2 μs
110: 102.4 μs
111: 204.8 μs
NSTPRE2 - 0
