Description
Unused
Return 0.
Programming Mode Related Setting Error Detect
Returns the check result of whether the signal input to
the FWE pin is high and whether the error protection
state is not entered.
When a low-level signal is input to the FWE pin or the
error protection state is entered, 1 is written to this bit.
The input level to the FWE pin and the error protection
state can be confirmed with the FWE bit (bit 7) and the
FLER bit (bit 4) in FCCS, respectively. For conditions to
enter the error protection state, see section 17.6.3,
Error Protection.
0: FWE and FLER settings are normal (FWE = 1, FLER
= 0)
1: FWE = 0 or FLER = 1, and programming cannot be
performed
