The FTMRG16K1 module provides the modes of operation normal and special . The operating mode is
determined by module-level inputs and affects the FCLKDIV, FCNFG, and EEPROT registers (see

21.4.4.1
Prior to issuing any Flash program or erase command after a reset, the user is required to write the
FCLKDIV register to divide BUSCLK down to a target FCLK of 1 MHz.
