IFCLK on
CY7C68013A
and
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.

Input
N/A INT4 isthe8051INT4interruptrequestinputsignal. The
INT4 pin is edge-sensitive, active HIGH.
N/A INT5# is the 8051 INT5 interrupt request input signal.
The INT5 pin is edge-sensitive, active LOW.
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.

N/A 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.
N/A 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.
