Description

RXP

High-Speed CML Signal Input(Main-Link)

RXN

High-Speed CML Signal Input(Main-Link)

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/

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

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.

LOCKN/

MSSEL

LOCKN : Lock Detect Output when PDN1=0. Must be connected

to Tx LOCKN with 10kΩ pull-up resistor.

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

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.
