Notes 1: P11 is measured when the P11/TXD1 P-channel output disable bit of the UART control register (bit 4 of address 001B16) is “0”.

2: RXD1, SCLK1, SCLK2, SDATA2, INT0, and INT1 have hysteresises only when bits 0 to 2 of the port P1P3 control register are set to “0” (CMOS level).

3: It is available only when operating key-on wake up.
