HFSEL/RCMP 61
CB/I HFSEL : High Frequency Mode select when PDN1=0.
0 : High Frequency Mode Disable
1 : High Frequency Mode Enable
RCMP : CML Signal Bi-directional Input/Output(Sub-Link) when
PDN1=1.
MAINMODE/ 60
RCMN
CB/I MAINMODE : Setting V-by-One® HS Mode or Sync Free Mode
when PDN1=0
0 : V-by-One® HS Mode
1 : Sync Free Mode
RCMN : CML Signal Bi-directional Input/Output(Sub-Link)
when PDN1=1.
HTPDN/
SUBMODE
54
55
BO HTPDN : Hot Plug Detect Output when PDN1=0. Must be
connected to Tx HTPDN with 10kΩ pull-up resistor.
SUBMODE : Sub-Link Mode Select when PDN1=1.
0 : 2-wire serial I/F Mode (default No Clock Stretching mode)
1 : Low Speed Data Bridge Mode
Forbid setting 1 when connecting with THCV231.
BO LOCKN : Lock Detect Output when PDN1=0. Must be connected
to Tx LOCKN with 10kΩ pull-up resistor.
LOCKN/
MSSEL
MSSEL : Sub-Link Master/Slave Select when PDN1=1.
0 : Sub-Link Master side(inside 2-wire serial I/F is slave)
1 : Sub-Link Slave side(inside 2-wire serial I/F is master)
Sub-Link Master is connected to HOST MPU.
Forbid setting 1 when connecting with THCV231.
LATEN/SD3/
AIN1/GPIO0
11
B
LATEN : Latch select input under Field BET(Main-Link or
Sub-Link).
0 : NOT Latched result
1 : Latched result
SD3
: Sub-Link Data Input/Output when PDN1=1 and
SUBMODE=1.
When Sub-Link is Master (MSSEL=0), SD3 is output.
When Sub-Link is Slave (MSSEL=1), SD3 is input.
AIN1 : Device ID setting for 2-wire serial I/F when
SUBMODE=0 and MSSEL=0. See Table 18.
GPIO0 : General Purpose Input/Output when SUBMODE=0 and
MSSEL=1.
When GPIO0 is used as Open-Drain Output, it must be connected
with a pull-up resistor to VDD.
When GPIO0 is used as push pull output or input, no external
component is required.
