C8051F96x
1.2. Port Input/Output
Digital and analog resources are available through 57 I/O pins (C8051F960/2/4/6/8) or 34 I/O pins
(C8051F961/3/5/7/9). Port pins are organized as eight byte-wide ports. Port pins can be defined as digital
or analog I/O. Digital I/O pins can be assigned to one of the internal digital resources or used as general
purpose I/O (GPIO). Analog I/O pins are used by the internal analog resources. P7.0 can be used as GPIO
and is shared with the C2 Interface Data signal (C2D). See Section “34. C2 Interface” on page 486 for
more details.
The designer has complete control over which digital and analog functions are assigned to individual port
pins. This resource assignment flexibility is achieved through the use of a Priority Crossbar Decoder. See
Section “27. Port Input/Output” on page 351 for more information on the Crossbar.
For Port I/Os configured as push-pull outputs, current is sourced from the VIO, VIORF, or VBAT supply pin.
Port I/Os used for analog functions can operate up to the supply voltage. See Section “27. Port Input/Out-
put” on page 351 for more information on Port I/O operating modes and the electrical specifications chap-
ter for detailed electrical specifications.
