Table 22. Remote side 2-wire serial slave register Write Procedure for 16bit register address
Step
Description
R/W Address
Set slave address of remote side 2-wire serial slave device (Low-order 7bits),
1
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
Set slave address of access target 2-wire serial slave (choose the value set in
4
W
0x04-0x0B[6:0]), and set 1 to 0x20 bit7.
0x20
Set the byte number written to remote side 2-wire serial slave (Max 16byte).
5
(Byte number = register value + 1)
W
0x21
Set the low-order bits([7:0]) of start address of remote side 2-wire serial slave register
6
W
to write.
0x27
Set the high-order bits([15:8]) of start address of remote side 2-wire serial slave
7
W
register to write.
0x28
Write 1 to WR_START_16B. (Start write access to remote side 2-wire serial slave
8
W
register)
0x2B (*1)
9 2-wire serial slave of Sub-Link Master perform clock stretching until remote side 2-wire
-
-
(*2) serial slave register access is completed.
9 When write access is completed, 2WIRE_ACS_END_INT register value become 1
-
-
(*3) and interrupt occurs (INT=H → L).
10 If write access was normally ended, read value should be “0x1”.
R
0x02
11 Repeat from step2 to step10 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)
