Notes 1: P11 is measured when the P11/TXD1 P-channel output disable bit of the UART1 control register (bit 4 of address 001B16) is “0”.

P05 is measured when the P05/TXD2 P-channel output disable bit of the UART2 control register (bit 4 of address 003116) is “0”.

2: RXD1, SCLK1, INT0, and INT1 (P36 selected) 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.
