32 / 80 page  HD404339 Series 30 I/O Ports The MCU has 53 input/output pins (D 0–D13, R00–R93) and one input-only pin (RA1). • The 30 pins consisting of ports D 0–D13, R1, R2, R8, and R9 are all high-voltage I/O pins. RA1 is a high- voltage input-only pin. The high-voltage pins can be equipped with or without pull-down resistance, as selected by the mask option. • All standard voltage output pins are CMOS output pins. However, the R0 2/SO pin can be programmed for NMOS open-drain output. • In stop mode, input/output pins go to the high-impedance state. • All standard voltage input/output pins have pull-up MOS built in, which can be individually turned on or off by software (Table 5). Pull-up MOS on/off settings can be made independently of settings as on-chip supporting module pins.
