(PD0)
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[8]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[9]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[10]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[11]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[12]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[13]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[14]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by the IFCONFIG[1:0] and
EPxFIFOCFG.0 (wordwide) bits.
FD[15]
is the bidirectional FIFO/GPIF data bus.
Multiplexed pin whose function is selected by IFCONFIG[1:0].
RDY0
is a GPIF input signal.
SLRD
is the input only read strobe with programmable polarity (FIFOPIN-
POLAR.3) for the slave FIFOs connected to FD[7:0] or FD[15:0].
Multiplexed pin whose function is selected by IFCONFIG[1:0].
RDY1
is a GPIF input signal.
SLWR
is the input only write strobe with programmable polarity (FIFOPIN-
POLAR.2) for the slave FIFOs connected to FD[7:0] or FD[15:0].
Multiplexed pin whose function is selected by IFCONFIG[1:0].
CTL0
is a GPIF control output.
FLAGA
is a programmable slave FIFO output status flag signal.
Defaults to programmable for the FIFO selected by the FIFOADR[1:0] pins.
Multiplexed pin whose function is selected by IFCONFIG[1:0].
CTL1
is a GPIF control output.
FLAGB
is a programmable slave FIFO output status flag signal.
Defaults to FULL for the FIFO selected by the FIFOADR[1:0] pins.
Multiplexed pin whose function is selected 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 or 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.
