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.
INT4 is the 8051 INT4 interrupt request input signal. The INT4 pin is edge-
sensitive, active HIGH.
INT5# is the 8051 INT5 interrupt request input signal. The INT5 pin is edge-
sensitive, active LOW.
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.
T1 is the active-HIGH T1 signal for 8051 Timer1, which provides the input
to Timer1 when C/T1 is 1. When C/T1 is 0, Timer1 does not use this bit.
T0 is the active-HIGH T0 signal for 8051 Timer0, which provides the input
to Timer0 when C/T0 is 1. When C/T0 is 0, Timer0 does not use this bit.
RXD1is an active-HIGH input signal for 8051 UART1, which provides data
to the UART in all modes.
TXD1is an active-HIGH output pin from 8051 UART1, which provides the
output clock in sync mode, and the output data in async mode.
RXD0 is the active-HIGH RXD0 input to 8051 UART0, which provides data
to the UART in all modes.
TXD0 is the active-HIGH TXD0 output from 8051 UART0, which provides
the output clock in sync mode, and the output data in async mode.
CS# is the active-LOW chip select for external memory.
WR# is the active-LOW write strobe output for external memory.
RD# is the active-LOW read strobe output for external memory.
OE# is the active-LOW output enable for external memory.
Reserved. Connect to ground.
USB Wakeup. If the 8051 is in suspend, asserting this pin starts up the
oscillator and interrupts the 8051 to allow it to exit the suspend mode.
Holding WAKEUP asserted inhibits the EZ-USB FX1 chip from suspending.
This pin has programmable polarity (WAKEUP.4).
