C8051F93x-C8051F92x
as GPIO and is shared with the C2 Interface Data signal (C2D). See Section “27. C2 Interface” on
page 319 for more details.
The designer has complete control over which digital and analog functions are assigned to individual Port
pins, 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 216 for more information on the Crossbar.
All Port I/Os are 5 V tolerant when used as digital inputs or open-drain outputs. For Port I/Os configured as
push-pull outputs, current is sourced from the VDD/DC+ supply. Port I/Os used for analog functions can
operate up to the VDD/DC+ supply voltage. See Section “21.1. Port I/O Modes of Operation” on page 213
for more information on Port I/O operating modes and the electrical specifications chapter for detailed elec-
trical specifications.
1.3.
The C8051F93x-C8051F92x Family includes an SMBus/I
baud rate configuration, and two Enhanced SPI interfaces. Each of the serial buses is fully implemented in
hardware and makes extensive use of the CIP-51's interrupts, thus requiring very little CPU intervention.
