necessary, the PLL Clock can be re-programmed for other quartz crystal frequencies within a range

from 23 to 30 MHz. Other quartz crystal frequencies can be programmed on your demand.

Note:

A Crystal Frequency change is compatible with other default I²C programming including the built-in

Automatic Standard Recognition System.

EN_PROG

FS1 programmation enable

0: FS1 I2C registers programmation ignored by system - FS1 pre-programmed automatically by

SYS-CONFIG register (normal use with standard quartz of 27 MHz)

1: FS1 I2C registers programmation used by system - FS1 pre-programmation by SYS-CONFIG

desactivated (to be used in case of no standard quartz, different from 27 MHz)
