1.1.2 Differences between Groups
Table 1.1 lists the Differences between Groups, Table 1.2 lists the Programmable I/O Ports Provided for Each
Group, and Table 1.3 lists the LCD Display Function Pins Provided for Each Group. Figures 1.9 to 1.13 show
the Pin Assignment for Each Group, and Tables 1.7 to 1.10 list Product Information.
The explanations in the chapters which follow apply to the R8C/L3AC Group only. Note the differences shown
below.
Note:
1. I/O ports are shared with I/O functions, such as interrupts or timers.
Refer to Tables 1.11 to 1.13, Pin Name Information by Pin Number, for details.
