V
Clock Generator Module (CGMB)
1.4.7 External Filter Capacitor Pin (CGMXFC)
CGMXFC is an external filter capacitor connection for the CGM. See
(CGMB)
1.4.8 Port A Input/Output (I/O) Pins (PTA7/KBD7:PTA0/KBD0)
Port A is an 8-bit bidirectional I/O port. Any or all of the port pins can be programmed to serve as external
interrupt pins. See
1.4.9 Port B I/O Pins (PTB7:PTB4, PTB3/AD3:PTB0/AD0)
Port B is an 8-bit bidirectional I/O port that shares four of its pins with the analog-to-digital converter.
