External Clock Input — Crystal Oscillator Option
. The external clock source is connected to
XTAL and the EXTAL pin is grounded or configured as GPIO while CLK_MOD bit in OSCTL register is set. The external
clock input must be generated using a relatively low impedance driver with maximum frequency less than 8 MHz.
