IMPORTANT
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.
• When the JP1 is set to VCC1>2, the voltage of VCC2 on the target system should
be 3.3 V or more.
• If using a CPU clock frequency of 30 MHz or more when the voltage of VCC1 is
higher than that of VCC2, set the SFR area of the intelligent I/O function to 2-wait
(set the PM13 bit to "1") when reading this area. This precaution only needs to be
observed when using an emulator, and does not apply for the actual MCU.
Notes on Switch SW5:
• When using this product in memory expansion mode or microprocessor mode, be
sure to set the SW5 same as the factory-setting (all 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, 0 : 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 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, 0 : 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 target system, the A-D converter operates differently from an actual MCU.
Make the final evaluation of the A-D converter using an actual MCU.
