Chapter 5 Port Functions; Port Configuration - NEC Renesas V850/SC1 User Manual

5.1 Port Configuration

The V850/SC1, V850/SC2, and V850/SC3 include 124 I/O port pins from ports 0 to 15 and 17 (12 port pins are
input only).
There are six pin I/O buffer power supplies; PORTV
described below.

Notes 1. The electrical specifications differ between an operating frequency of 4 to 17 MHz and an operating
frequency of 4 to 20 MHz.
