To write the flash memory on-board, connectors that connect the dedicated flash memory programmer must be
When the flash memory programming mode is set, all the pins not used for programming the flash memory are in the
Directly connect this pin to a flash memory programmer when data is written by the flash memory programmer. This

The FLMD0 pin does not have to be pulled down externally because it is internally pulled down by reset. To pull it
down externally, use a resistor of 1 kΩ to 200 kΩ.
It is recommended to leave this pin open during normal operation.
The FLMD0 pin must always be kept at the V

FLMDPUP = “0”, default value) by using bit 7 (FLMDPUP) of the background event control register (BECTL) (see 27.5
(1) Back ground event control register). To pull it down externally, use a resistor of 200 kΩ or smaller.
Self programming and the rewriting of flash memory with the programmer can be prohibited using hardware, by
directly connecting this pin to the V
It is recommended to leave this pin open when using the self programming function. To pull it down externally, use a
resistor of 100 kΩ to 200 kΩ.
In the self programming mode, the setting is switched to pull up in the self programming library.
