7.8 Test Pins on the board
In order to connect external devices and enable MCU functions, test pins from MCU ports are grouped on the lower left
area of the evaluation board, as shown in Figure 14
and Figure 15 . Test Pin (TP) No. and corresponding port functions
are listed in
Table 9
.
A protection circuit is mounted on the board for the A/D input pins (AN0, AN1) and a pull-up resistor is mounted on
the board for INT (TP4), PULSE (TP3), SSO(TP17), SCS(TP18), SSCLK(TP19) and SSI(TP20) pins. For details on
how to use each MCU peripheral function, refer to the R8C/34U Group, R8C/34K Group User’s Manual: Hardware.
When you connect the external device to this product through test pins, be careful not to short signal
lines or between power line and ground. If this product is revised by the user, operation cannot be
guaranteed.
