CHAPTER 2 PIN FUNCTIONS
2.1
List of Pin Functions
The names and functions of the pins in the V850ES/SG2 and V850ES/SG2-H are described below.
There are four types of pin I/O buffer power supplies: AVREF0, AVREF1, BVDD, and EVDD. The relationship between
these power supplies and the pins is described below.

Notes 1. Fix this pin to low level from when the reset status has been released until the OCDM.OCDM0 bit is
cleared (0) when the on-chip debug function is not used. For details, see 4.6.3 Cautions on on-chip
debug pins. A pull-down resistor is incorporated. It can be disconnected by clearing the OCDM.OCDM0
bit to 0.
2. Flash memory versions only
Remark
GF: 100-pin plastic QFP (14
