O/Z H L Multiplexed pin whose function is selected by the
following bits:
IFCONFIG[1..0].
CTL2 is a GPIF control output.
FLAGC is a programmable slave-FIFO output
status flag signal.
Defaults to EMPTY for the FIFO selected by the
FIFOADR[1:0] pins.

Interface Clock, used for synchronously clocking
data into or out of the slave FIFOs. IFCLK also
serves as a timing reference for all slave FIFO
control signals and GPIF. When internal clocking is
used (IFCONFIG.7 = 1) the IFCLK pin can be
configured to output 30/48 MHz by bits IFCONFIG.5
and IFCONFIG.6. IFCLK may be inverted, whether
internally or externally sourced, by setting the bit
IFCONFIG.4 =1.

PE0 is a bidirectional I/O port pin.
28 22 – – – INT4 Input N/A N/A INT4 is the 8051 INT4 interrupt request input signal.
The INT4 pin is edge-sensitive, active HIGH.
106 84 – – – INT5# Input N/A N/A INT5# is the 8051 INT5 interrupt request input
signal. The INT5 pin is edge-sensitive, active LOW.
31 25 – – – T2 Input N/A N/A T2 is the active HIGH T2 input signal to 8051
Timer2, which provides the input to Timer2 when
C/T2 = 1. When C/T2 = 0, Timer2 does not use this
pin.
