Directly connect this pin to a flash memory programmer when data is written by the flash memory programmer.
This supplies a writing voltage of the V
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
externally because it is internally pulled down by reset. However, pulling it down must be kept selected (i.e.,
FLMDPUP = “0”, default value) by using bit 7 (FLMDPUP) of the background event control register (BECTL) (see
23.5 (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
