IICM: Bit in U2SMR register
IICM2, SWC, SWC2, SDHI: Bits in U2SMR2 register
STSPSEL, ACKD, ACKC: Bits in U2SMR4 register
The above applies when:
Note:
• Bits SMD2 to SMD0 in U2MR register = 010b
• IICM bit in U2SMR register = 1
1. When the IICM bit is set to 1, the pin level can be read even if the port direction bit corresponding to the SCL2 pin is set to 1 (output mode).
