1. Overview
This MCU is built using the high-performance silicon gate CMOS process using the R8C CPU core and is packaged
in a 48-pin plastic molded LQFP. This MCU operates using sophisticated instructions featuring a high level of
instruction efficiency. With 1 Mbyte of address space, it is capable of executing instructions at high speed. This MCU
is equipped with one CAN module and suited to in-vehicle or FA networking.
Furthermore, the data flash (1 KB x 2 blocks) is embedded in the R8C/23 Group.
The difference between R8C/22 and R8C/23 Groups is only the existence of the data flash. Their peripheral functions
are the same.

2. Central Processing Unit (CPU)
2.8.7 Interrupt Enable Flag (I)
The I flag enables a maskable interrupt.
An interrupt is disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to
0 when an interrupt request is acknowledged.
2.8.8 Stack Pointer Select Flag (U)
ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.
The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software
interrupt numbers. 0 to 31 is executed.
2.8.9 Processor Interrupt Priority Level (IPL)
IPL, 3 bits wide, assigns processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has greater priority than IPL, the interrupt is enabled.
2.8.10 Reserved Bit
If necessary, set to 0. When read, the content is undefined.
