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