Note there are no limitations regarding user RAM however, 2k bytes of user Flash ROM are
utilized by the kernel.
6.4 Status After Reset
Table 6-2 lists the value of the UART1 register initialized by the kernel when the Mini R8C starter
board is reset. The register status depends on the MCU’s internal operation performed after a
reset.

6.5 Register Operation Limitations
Table 6-3 lists registers with modification limitations. Modifying the contents of these registers are
modified may cause the kernel to operate incorrectly.
