On-Board Programming Mode

When the EMLE pin is set to low level, the mode pins (MD0, MD1, MD2, and MD3) are set to

on-board programming mode and the reset start is executed, a transition is made to on-board

programming mode in which the on-chip flash memory can be programmed/erased. On-board

programming mode has three operating modes: SCI boot mode by PM2 setting, user boot mode,

and user program mode, according to PM2 setting.

Table 25.5 shows the pin setting for each operating mode. For details on the state transition of

each operating mode for flash memory, see figure 25.2.
