to write H'FF to the entire key code area. If data other than H'FF is to be written to the key
code area in programmer mode, a verification error will occur unless a countermeasure is taken

frequency is 20 MHz, the download for each program takes approximately TBD μs at the
maximum.
microcomputer which does not support download of the on-chip program by a SCO transfer
request cannot run in this LSI. Be sure to download the on-chip program to execute

periodic timer interrupts) for the WDT with taking the programming/erasing time into
consideration as required.
