Section 22 Flash Memory
22.8
When the reset start is executed with a low level input to the EMLE pin and the mode pins (MD0,
MD1, and MD2) set to on-board programming mode, 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: boot mode, user boot mode, and user program
mode.
Table 22.5 shows the pin setting for each operating mode. For details on the state transition of
each operating mode for flash memory, see figure 22.2.
Table 22.5 On-Board Programming Mode Setting
22.8.1
Boot mode executes programming/erasure of the user MAT or user boot MAT by means of the
control command and program data transmitted from the externally connected host via the on-chip
SCI_4.
In boot mode, the tool for transmitting the control command and program data, and the program
data must be prepared in the host. The serial communication mode is set to asynchronous mode.
The system configuration in boot mode is shown in figure 22.6. Interrupts are ignored in boot
mode. Configure the user system so that interrupts do not occur.
