Port R1 is multiplexed with various special features.The
control registers controls the selection of alternate func-
tion. After reset, this value is “0”, port may be used as nor-
mal I/O port. The way to select alternate function such as
comparator input or buzzer will be shown in each periph-
eral section.

In addition, R1 port is used as key scan function which op-
erate with normal input port.

Input or output is configured automatically by each func-
tion register (KSMR) regardless of R1DR.

R2 Port

R2 is a 4-bit CMOS bidirectional I/O port (address 0C2

H

).

Each I/O pin can independently used as an input or an out-
put through the R2DR register (address 0CA

H

).

R2 has internal pull-ups that is independently connected or
disconnected by R2PU (address 0D2

H

). The control regis-

ters for R2 are shown as below.

R3 Port

R3 is a 4-bit CMOS bidirectional I/O port (address 0C3

H

).

Each I/O pin can independently used as an input or an out-
put through the R3DR register (address 0CB

H

).

SEG0~SEG36

Segment signal output pins for the LCD display. See "19.
LCD DRIVER" on page 71 for details.

COM0~COM3

Common signal output pins for the LCD display. See "19.
LCD DRIVER" on page 71 for details.

SEG34~SEG36 and COM1~COM3 are selected by LCDD
of the LCR register.
