(3) Registers controlling SMB0
SMB0 is controlled with the following 5 registers.
SMB control register 0(SMBC0)
SMB status register 0 (SMBS0)
SMB clock selection register 0 (SMBCL0)
SMB mode register 0 (SMBM0)
SMB input level setting register 0 (SMBVI0)
The following additional registers are also used.
SMB shift register 0 (SMB0)
Slave address register 0 (SMBSVA0)
(a) SMB control register 0 (SMBC0)
This register sets SMB operation enable/disable, the wait timing, and other SMB operations.
SMBC0 is manipulated with a 1-bit or 8-bit memory manipulation instruction.
A RESET input clears SMBC0 to 00H.
