Section 9 I/O Ports
9.10.4 Pin Functions
Port L pins also function as LCD driver segment output pins (SEG24 to SEG17). Port L pin
functions are shown below.
• PLn/SEGn + 17
The pin function is switched as shown below according to the combination of the SGS3 to
SGS0 bits in LPCR of the LCD driver/controller and PLnDDR bit.

9.11 Port M (H8S/2268 Group Only)
Port M is an 8-bit I/O port and has the following registers.
• Port M data direction register (PMDDR)
• Port M data register (PMDR)
• Port M register (PORTM)
