Terminal Functions (continued) TERMINAL INTERNAL TYPE(1)(2) PULLUP/ DESCRIPTION PIN NAME PULLDOWN(3) NUMBER GENERAL-PURPOSE I/O (GIO) GIOA[0]/INT0 28 3.3-V I GIOA[1]/INT1/ 29 ECLK GIOA[2]/INT2 30 GIOA[3]/INT3 31 General-purpose input/output pins. GIOA[4]/INT4 25 GIOA[0]/INT[0] is an input-only pin. GIOA[7:0]/INT[7:0] are GIOA[5]/INT5 24 interrupt-capable pins. GIOA[6]/INT6 23 GIOA[1]/INT[1]/ECLK pin is multiplexed with the external clock-out GIOA[7]/INT7 22 3.3-V I/O IPD function of the external clock prescale (ECP) module. GIOB[0] 16 GIOB[1] 15 GIOB[2] 14 GIOB[3] 13 MULTI-BUFFERED ANALOG-TO-DIGITAL CONVERTER (MibADC) MibADC event input. ADEVT can be programmed as a GIO pin.The ADEVT pin can also be used as a user-selectable event source to event trigger the MibADC event group or group1 if the associated ADEVT 66 3.3-V I/O register source bits are properly configured and defined. For the internal device connections, see the MibADC section of this data sheet.
