It is recommended to leave this pin open during normal operation.
The FLMD0 pin must always be kept at the V
down 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 24.5 (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.
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.
