Slow clock selection for watchdog timer:
Set
by the user to use the internal 32kHz for the timer. This bit must be set to use watchdog timer if there
is no external crystal
Cleared
by user to use the external 32kHz crystal

Fast interrupt response bit
Set
by user to enable the fast interrupt response. If an interrupt occurs when FINT is set, the CPU will run
at the fastest clock frequency in the interrupt service routine. After completing the ISR, execution resumes
at the clock speed set by the CD bits
Cleared
by user to disable the fast interrupt response
