(d) SMB mode register 0 (SMBM0)
SMBM0 is used to specify SCL0 level control and interrupt control.
SMBM0 is manipulated using a 1-bit or 8-bit memory manipulation instruction.
A RESET input loads 20H into SMBM0.
Figure 6-41. Format of SMB Mode Register 0 (1/2)
Notes 1.
If SCL0 is made low with SCLCTL0, wait state cannot be released with WREL0.
2.
When an extension code is received (EXC0 = 1), wait state is forcibly set in the 8th clock period.
3.
During address transfer, the master waits in the 9th clock period.
SCLCTL0
SCL level control
Note 1
SCL0 is held low.
When SCL0 is high, SCL0 is held low after waiting until SCL0 is made low.

AWTIM0
At the slave, an interrupt request is generated on the falling edge of the 9th clock period when an address
match (COI0 = 1) is found during address data reception.
The clock is pulled low to cause the master to wait.
