Common Control Registers (Read/Write)
30A00
[0:1] TCKSELA
00
Transmit Clock Select. Controls source of 78 MHz TCK78 for SERDES
quad A
01 = Channel AC
11 = Channel AD
[2:3] RCKSELA
Receive Clock Select. Controls source of 78 MHz RCK78 for SERDES
quad A
01 = Channel AC
11 = Channel AD
[4:5] TCKSELB
Transmit Clock Select. Controls source of 78 MHz TCK78 for SERDES
quad B
01 = Channel BC
11 = Channel BD
[6:7] RCKSELB
Receive Clock Select. Controls source of 78 MHz RCK78 for SERDES
quad B
01 = Channel BC
11 = Channel BD
30A01
[0:4]
00
Reserved for future use
[5:7] RX_FIFO_MIN
LSb’s for the threshold for low address in RX_FIFOs. RX_FIFO_MIN, Bit
5 is LSb.*
30A02
[0:1] RX_FIFO_MIN
00
MSb’s for the threshold for low address in RX_FIFOs. RX_FIFO_MIN, Bit
1 is MSb.*
[2]
FMPU_RESYNC4
Resynchronize a four-channel group. When FPMPU_RESYNC4 transi-
tions from 0 to 1, the entire four-channel group is resynchronized.
FMPU_RESYNC4 = 0 on device reset
[3:7]
Reserved for future use
Common Status Registers
30A03
[0]
SYNC4_OVFL
00
Read-Only Multi-Channel Overow Status. When SYNC4_OVFL=1, 4-
channel synchronization FIFO overow has occurred. SYNC4_OVFL=0
on device reset.
[1]
SYNC4_OOS
Read-Only Multi-Channel Out-Of-Sync Status. When SYNC4_OOS=1,
4-channel synchronization has failed. SYNC4_OOS=0 on device reset.
[2:7]
Reserved for future use.
* Useful values for RX_FIFO_MIN [0:4] are 0 to 17(decimal)
