The Flash frequency high and low byte registers combine to form a 16-bit value, FFREQ,
to control timing for Flash Program and Erase operations. The 16-bit binary Flash
frequency value must contain the system clock frequency (in KHz) and is calculated using
the following equation.
FFREQH—Flash frequency high byte
High byte of the 16-bit Flash frequency value.
FFREQL—Flash frequency low byte
Low byte of the 16-bit Flash frequency value.
Flash programming and erasure is not supported for system clock frequencies below
10 kHz or above 20 MHz. The Flash frequency high and low byte registers must be
loaded with the correct value to ensure proper operation of the device.
