Table 2-55. Register 2D Field Descriptions (continued)
Bit Field Type Reset Description
1-1
FBAB_SIG_INVALI
D_RD_OVR
R/W 0h
FOR LOW POWER CONSUMPTION:
ASYNC FIFOs are gated based on sig-invalid from TDD
controller.
Use this register to override this behavior, by setting ovr =1
0-0
FBAB_SIG_INVALI
D_RD_VAL
R/W 0h
FOR LOW POWER CONSUMPTION:
When FBAB_SIG_INVALID_RD_OVR is 1,
setting this register val = 0, gates the data
setting to val = 1, ungates the data
2.3.12 Register 2Eh (offset = 2Eh) [reset = 0h]

USE_OTHER_INST_CLK_EN
R/W-0h
LEGEND: R/W = Read/Write; W = Write only; -n = value after reset

Bit Field Type Reset Description
1-0
USE_OTHER_INS
T_CLK_EN
R/W 0h
FOR LOW POWER CONSUMPTION:
0 -> no clk en mux
1 -> cd instance uses ab instance clks
2 -> ab instance uses cd instance clks

4-4
MUX_SEL_FOR_D
UC_TXB_TO_TXD
_CLK
R/W 0h
FOR LOW POWER CONSUMPTION:
(To switch off 2T_CD instance clocks completely if all the data
comes from the 4-lanes of 2T-AB instance).Use this mux b-pin
value along with 'mux_ovr_for_duc_clk'.
Use of LATTE configuration is recommended to set these
registers.
3-3
MUX_SEL_FOR_D
UC_TXB_TO_TXC
_CLK
R/W 0h
FOR LOW POWER CONSUMPTION:
(To switch off 2T_CD instance clocks completely if all the data
comes from the 4-lanes of 2T-AB instance).Use this mux b-pin
value along with 'mux_ovr_for_duc_clk'.
Use of LATTE configuration is recommended to set these
registers.

comes from the 4-lanes of 2T-AB instance).Use this mux b-pin
value along with 'mux_ovr_for_duc_clk'.
