21.3.1
In the user programming mode, the flash memory can be programmed by the CPU through
execution of software commands. In this mode, the user ROM and data flash can be programmed
without using a ROM programmer with the microcomputer mounted on a system board.
The programming and block erase commands should be executed only in each block area of the
user ROM and data flash.
The user programming mode provides the erase/write 0 mode (EW0 mode). Table 21.4 gives an
overview of the EW0 mode specifications.
Table 21.4 EW0 Mode Specifications
Notes: 1. Make sure that no interrupt (except NMI) or DMA transfer is generated.
