Notes on Switch JP1:

If using this product when the voltage of VCC1 is higher than that of VCC2, set the JP1 to VCC1>2.

If using this product when the voltage of VCC1 is higher than that of VCC2, the CPU clock must be 24

MHz or less.

Notes on Switch SW5:

When selecting the following MCU files in the Init dialog box of the emulator debugger to execute the

A/D conversion debug, note the following.

M32C PC7501 Emulator Debugger: m30870_ad.mcu

M3T-PD308F: m30870_ad_a.mcu

When using this product in memory expansion mode or microprocessor mode, be sure to set the all

SW5 to ON.

When setting the register below to use the analog input port selection function, you need to set the

direction register of port P15 for a pin that performs A/D conversion to "input".

And you need to set the function selection register of port P15 for a pin that performs A/D conversion to

"I/O port".

A/D0 control register 2 (address 394h)

b2, b1

1, 0 : AN00 to AN07

1, 1 : AN20 to AN27

Also, when the P0 group and P2 group are selected for A/D input, port P15 cannot be used as an I/O

port. When setting the register above, port P15 cannot be used as an I/O port even if A/D conversion is

halting.

When using the A/D converter in multi-port sweep mode, be sure to set the all SW5 to ON. When

setting the register below to use multi-port sweep mode, you need to set the direction register of port

P15 for a pin that performs A/D conversion to "input".

And you need to set the function selection register of port P15 for a pin that performs A/D conversion to

"I/O port".

A/D0 control register 4 (address 392h)

b3, b2

1, 0 : AN0 to AN7, AN00 to AN07

1, 1 : AN0 to AN7, AN20 to AN27

Also, when the P0 group and P2 group are used for multi-port sweep mode, port P15 cannot be used

as an I/O port. When setting the register above, port P15 cannot be used as an I/O port even if A/D

conversion is halting.

Because a converter board and other devices are used between the evaluation MCU and the user

system, the A/D converter operates differently from an actual MCU. Make the final evaluation of the A/D

converter using an actual MCU.
