Notes 1. Use of the area FEF00H to FF309H is prohibited when using the self-programming function and data flash
function, because this area is used for self-programming library.
2. R5F100xE only.
Caution When executing instructions from the RAM area while RAM parity error resets are enabled (RPERDIS
= 1), be sure to initialize the used RAM area + 10 bytes.
