Port 2 is an 8-bit I/O port; refer to port 0 for more information.

P2_BUF: Port 2 output buffer. When P2.n is configured as an output pin, it outputs the content of

P2_BUF.n.

P2: Port 2 pad value.

P2_CR: P2.0 ~ P2.7 is input or output. 0: input, 1: output

P2_MR: P2.0 ~ P2.7, pull-high and CMOS/NMOS

Port 3 is an 8-bit I/O port; refer to port 0 for more information.

P3_BUF: Port 3 output buffer. When P3.n is configured as an output pin, it outputs the content of

P3_BUF.n.

P3: Port 3 pad value.

P3_CR: P3.0 ~ P3.7 is input or output. 0: input, 1: output

P3_MR: P3.0 ~ P3.7, pull-high and CMOS/NMOS

When P3 port is used as input mode, it is an interrupt source, a falling edge at any pin will set the

IRQ_ST.P3.

The same event can release suspend mode (enable oscillator), and release halt

mode (resume Fcpu) if RLH_EN.P3 is set.

An interrupt subroutine will be executed if

IRQ_EN.P3 is set.

Port 4 is a 2-bit I/O port; refer to port 0 for more information.

P4_BUF: Port 4 output buffer. When P4.n is configured as an output pin, it outputs the content of

P4_BUF.n.

P4: Port 4 pad value.

P4_CR: P4.0 ~ P4.1 is input or output. 0: input, 1: output

P4_MR: P4.0 ~ P4.1, pull-high and CMOS/NMOS
