This bidirectional bus is high-impedance when inactive, input for bus reads, and output for bus writes. The data bus is used for external 8051 program and data memory. The data bus is active only for external bus accesses, and is driven LOW in suspend. 60 D1 I/O/Z Z61 D2 I/O/Z Z62 D3 I/O/Z Z63 D4 I/O/Z Z86 D5 I/O/Z Z87 D6 I/O/Z Z88 D7 I/O/Z Z39 PSEN# Output H Program Store Enable. This active-LOW signal indicates an 8051 code fetch from external memory. It is active for program memory fetches from 0x20000xFFFF when the EA pin is LOW, or from 0x00000xFFFF when the EA pin is HIGH. 34 28 BKPT Output L Breakpoint. This pin goes active (HIGH) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are en-abled in the BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT register is HIGH, this signal pulses HIGH for eight 12-/24-/48-MHz clocks. If the BPPULSE bit is LOW, the signal re-mains HIGH until the 8051 clears the BREAK bit (by writing 1 to it) in the BREAKPT register.99 77 49 42 RESET# Input N/A Active LOW Reset. Resets the entire chip. This pin is normally tied to VCCthrough a 100K resistor, and to GND through a 0.1-µF ca-pacitor. Note:5. Unused inputs should not be left floating. Tie either HIGH or LOW as appropriate. Outputs should only be pulled up or down to ensure signals at power-up and in standby.PIN DESCRIPTIONS OF IC CY7C680133 - 235 EA Input N/A External Access. This pin determines where the 8051 fetches code between addresses 0x0000 and 0x1FFF. If EA = 0 the 8051 fetches this code from its internal RAM. IF EA = 1 the 8051 fetches this code from external memory. 12 11 12 5 XTALIN Input N/A Crystal Input. Connect this signal to a 24-MHz parallel-resonant, fundamental mode crystal and 20-pF capacitor to GND. It is also correct to drive XTALIN with an external 24 MHz square wave derived from another clock source.11 10 11 4 XTALOUT Output N/A Crystal Output. Connect this signal to a 24-MHz parallel-resonant, fundamental mode crystal and 20-pF capacitor to GND.If an external clock is used to drive XTALIN, leave this pin open.1100 5 54 CLKOUT O/Z 12 MHz 12-, 24- or 48-MHz clock, phase locked to the 24-MHz input clock. The 8051 defaults to 12-MHz operation. The 8051 may tri-state this output by setting CPUCS.1 = 1.

If the 8051 is in suspend and WU2EN = 1, a transition on this pin starts up the oscillator and interrupts the 8051 to allow it to exit the sus-pend mode. Asserting this pin inhibits the chip from suspending, if WU2EN=1. 89 71 44 37 PA4 orFIFOADR0I/O/Z I(PA4)Multiplexed pin whose function is selected by: IFCONFIG1.0.PA4 is a bidirectional I/O port pin.FIFOADR0 is an input-only address select for the slave FIFOs con-nected to FD7.0 or FD15.0.90 72 45 38 PA5 orFIFOADR1I/O/Z I(PA5)Multiplexed pin whose function is selected by: IFCONFIG1.0.PA5 is a bidirectional I/O port pin.FIFOADR1 is an input-only address select for the slave FIFOs con-nected to FD7.0 or FD15.0.91 73 46 39 PA6 or PKTENDI/O/Z I(PA6)Multiplexed pin whose function is selected by the IFCONFIG1:0 bits.PA6 is a bidirectional I/O port pin.PKTEND is an input-only packet end with programmable polarity (FIFOPOLAR.5) for the slave FIFOs connected to F
