Read/Write access to remote side 2-wire serial slave devices connected to Sub-Link Slave Device 

  HOST MPU can access to remote side 2-wire serial slave register via Sub-Link Master and Sub-Link Slave by 

Sub-Link Master register settings. Sub-Link Slave has 2-wire serial master block. Up to 8 devices are 

connectable to 2-wire serial master of Sub-Link Slave device.

Remote side 2-wire serial slave register Write Procedure for 8bit register address 

Step

Description

R/W

Address

1 

Set slave address of remote side 2-wire serial slave device (Low-order 7bits), 

and enable this address (High-order 1bit). 

W 0x04-0x0B

2 

Write 1 or 0 and clear(auto clear) access status register (2WIRE_ACS_END_INT). 

W 

0x02 bit7

3 

Set the data for remote side 2-wire serial slave to write (Max 16byte). 

W 

0x10-0x1F

4 

Set slave address of access target 2-wire serial slave (choose the value set in 

0x04-0x0B[6:0]), and set 0 to 0x20 bit7. 

W 0x20 

5 

Set the byte number written to remote side 2-wire serial slave (Max 16byte). 

(Byte number = register value + 1) 

W 0x21 

6 

Set the start address of remote side 2-wire serial slave register to write. 

W 

0x23 

7 

Write 1 to WR_START_8B. (Start write access to remote side 2-wire serial slave 

register) 

W 0x25

 (*1)

 

8 

(*2) 

2-wire serial slave of Sub-Link Master perform clock stretching until remote side

2-wire serial slave register access is completed.

- - 

8 

(*3) 

When write access is completed, 2WIRE_ACS_END_INT register value become 1 

and interrupt occurs (INT=H 

→

 L). 

- - 

9 

If wire access was normally ended, read value should be “0x1”. 

R 

0x02 

10 

Repeat from step2 to step9 if needed. 

- 

- 

*1 It’s Prohibit that HOST MPU start access to Sub-Link Slave or remote 2-wire serial slave before the previous access to

Sub-Link Slave or remote side 2-wire serial slave is completed.

*2 When 2WIRE_MODE = 00 (Clock Stretching Mode)
*3 When 2WIRE_MODE = 01 (No Clock Stretching Mode)
