114 / 848 page  7. I/O Ports REJ09B0441-0010 Rev.0.10 Jul 30, 2008 Page 78 of 809 Under development Preliminary specification Specifications in this manual are tentative and subject to change. R8C/L35A Group, R8C/L36A Group, R8C/L38A Group, R8C/L3AA Group, R8C/L35B Group, R8C/L36B Group, R8C/L38B Group, R8C/L3AB Group 7. I/O Ports I/O ports are shared with the LCD ports for the LCD dive control waveform output and the I/O functions for the oscillation circuits, timers, and A/D converter. When these functions are not used, pins can be used as I/O ports. Table 7.1 lists the Overview of I/O Ports. The following explanation applies to the R8C/L33A Group and R8C/L3AB Group, which have the maximum number of I/O ports. For other groups, note that only the pins listed in Table 7.2 are provided. Notes: 1. In input mode, whether an internal pull-up resistor is connected or not can be selected by registers P0PUR to and P13PUR. 2. Whether the drive capacity of the output transistor is set to low or high can be selected by registers P10DRR and P11DRR. 3. The input threshold value can be selected among three voltage levels (0.35 VCC, 0.50 VCC, and 0.70 VCC) using registers VLT0 and VLT1. Note: 1. The symbol “ √” indicates a programmable I/O port.
