Section 8 I/O Ports; Table 8.1 Port Functions - Renesas H8S Series Hardware Manual

Table 8.1 is a summary of the port functions. The pins of each port also function as input/output
pins of peripheral modules and interrupt input pins. Each input/output port includes a data
direction register (DDR) that controls input/output and data registers (DR and ODR) that store
output data. DDR, DR, and ODR are not provided for an input-only port.
Ports 1 to 3, 6, and B to F have built-in input pull-up MOSs. Port 1 to 3, C, and D can drive LEDs
(with 5-mA current sink).
P52, P97, P86, P42, and ports A and G are NMOS push-pull output.
