UART2 Special Mode Register 2

Mitsubishi microcomputers
M16C / 30 Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Bit 0 of the UART2 special mode register 2 (address 037616) is used as the I2C mode select bit 2. Table
1.16.11 shows the types of control to be changed by I2C mode select bit 2 when the I2C mode select bit
is set to “1”. Table 1.16.12 shows the timing characteristics of detecting the start condition and the stop
condition. Set the start/stop condition control bit (bit 7 of UART2 special mode register 2) to “1” in I2C
mode.
