connection
When performing on-board writing, mount a connector on the target system to connect to the dedicated
flash programmer. Also, incorporate a function on-board to switch from the normal operation mode to
the flash memory programming mode.
In the flash memory programming mode, all the pins not used for flash memory programming become
the same status as that immediately after reset. Therefore, pin handling is required when the external
device does not acknowledge the status immediately after a reset.
(1)
FLMD0 pin
In the normal operation mode, input a voltage of V
SS3
level to the FLMD0 pin. In the flash memory
programming mode, supply a write voltage of V
DD3
level to the FLMD0 pin.
Because the FLMD0 pin serves as a write protection pin in the self programming mode, a voltage
of V
DD3
level must be supplied to the FLMD0 pin via port control, etc., before writing to the flash
memory. For details, refer to the self-programming application note (U16929E).
