1.3. Port Input/Output
Digital and analog resources are available through 19 (Si1000/1/2/3) or 16 (Si1004/5) I/O pins. Three addi-
tional GPIO pins are available through the EZRadioPRO peripheral. Port pins are organized as three byte-
wide ports. Port pins P0.0–P2.6 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. P1.0, P1.1, P1.2, and P1.4 are dedicated for communication with the EZRa-
dioPRO peripheral. P1.3 is not available. P2.7 can be used as GPIO and is shared with the C2 Interface
Data signal (C2D). See Section “29. C2 Interface” on page 371 for more details.
The designer has complete control over which digital and analog functions are assigned to individual port
pins and is limited only by the number of physical I/O pins. This resource assignment flexibility is achieved
through the use of a Priority Crossbar Decoder. See Section “21.3. Priority Crossbar Decoder” on
page 211 for more information on the crossbar.
All Px.x Port I/Os are 5 V tolerant when used as digital inputs or open-drain outputs. For Port I/Os config-
ured as push-pull outputs, current is sourced from the VDD_MCU supply. Port I/Os used for analog func-
tions can operate up to the VDD_MCU supply voltage. See Section “21.1. Port I/O Modes of Operation” on
page 208 for more information on Port I/O operating modes and the electrical specifications chapter for
detailed electrical specifications.
