1. Overview
1.6 Pin Description
Table 1.10 Pin Description (100-pin and 128-pin Version) (1)
Apply 2.7 to 5.5 V to the VCC1 and VCC2 pins and 0 V to the VSS pin. The VCC
apply condition is that VCC1
≥ VCC2.(2)
Applies the power supply for the A/D converter. Connect the AVCC pin to
VCC1. Connect the AVSS pin to VSS.
The microcomputer is in a reset state when applying "L" to the this pin.
Switches processor mode. Connect this pin to VSS to when after a reset to start
up in single-chip mode. Connect this pin to VCC1 to start up in microprocessor
mode.
Switches the data bus in external memory space. The data bus is 16 bits long
when the this pin is held "L" and 8 bits long when the this pin is held "H". Set it
to either one. Connect this pin to VSS when an single-chip mode.
Inputs and outputs data (D0 to D7) when these pins are set as the separate bus.
Inputs and outputs data (D8 to D15) when external 16-bit data bus is set as the
separate bus.
Output address bits (A0 to A19).
Input and output data (D0 to D7) and output address bits (A0 to A7) by time-
sharing when external 8-bit data bus are set as the multiplexed bus.
Input and output data (D0 to D7) and output address bits (A8 to A15) by time-
sharing when external 16-bit data bus are set as the multiplexed bus.
________
Output CS0 to CS3 signals. CS0 to CS3 are chip-select signals to specify an
external space.

______
Output WRL, WRH, (WR, BHE), RD signals. WRL and WRH or BHE and WR
can be switched by program.
________ _________
_____
WRL, WRH and RD are selected
________
The WRL signal becomes "L" by writing data to an even address in an external
memory space.
_________
The WRH signal becomes "L" by writing data to an odd address in an external
memory space.
_____
The RD pin signal becomes "L" by reading data in an external memory space.
______ ________
_____
WR, BHE and RD are selected
______
The WR signal becomes "L" by writing data in an external memory space.
_____
The RD signal becomes "L" by reading data in an external memory space.
________
The BHE signal becomes "L" by accessing an odd address.
______ ________
_____
Select WR, BHE and RD for an external 8-bit data bus.
ALE is a signal to latch the address.
__________
While the HOLD pin is held "L", the microcomputer is placed in a hold state.
_________
In a hold state, HLDA outputs a "L" signal.
________
While applying a "L" signal to the RDY pin, the microcomputer is placed in a wait
state.

Power Supply : Power supplies which relate to the external bus pins are separated as VCC2, thus they can be inter-
faced using the different voltage as VCC1.
NOTES:
1. In this manual, hereafter, VCC refers to VCC1 unless otherwise noted.
2. In M16C/62PT, apply 2.7 to 5.5 V to the VCC1 and VCC2 pins. Also the apply condition is that VCC1
≥ VCC2.
3. When use VCC1 > VCC2, contacts due to some points or restrictions to be checked.
4. Bus control pins in M16C/62Tcannot be used.
