External FP pin status bit
The Flash Mode Register (FMOD) is a read-only status register, with its FPMOD bit indicating the FP (Flash
Protect) pin status.
The internal flash memory is enabled for programming or erase operation only when FPMOD = "1", and is
protected against programming or erase operation when FPMOD = "0".
