TX.................This bit selects the pin function of No.47.
“0” : EAPD
“1” : DIT
EXEN ...........This bit selects whether EXT24M pin outputs clock or not.
“0” : EXT24M is power down state, and outputs low level.
“1” : EXT24M outputs clock.
The bits except TX and EXEN should not be changed from the default value.
