128		100	56	56	56 VF-	Name	Type	Default	Description
TQFP	TQFP		SSOP	QFN	BGA
34		28				BKPT	Output	L	Breakpoint. This pin goes active (HIGH) when the 8051
									address bus matches the BPADDRH/L registers and
									breakpoints are enabled 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 remains HIGH until the 8051 clears the BREAK
									bit (by writing 1 to it) in the BREAKPT register.
99		77	49	42	8B	RESET#	Input	N/A	Active LOW Reset. Resets the entire chip. See section
									3.9 ”Reset and Wakeup” on page 6 for more details.
35						EA	Input	N/A	External Access. This pin determines where the 8051
									fetches code between addresses 0x0000 and 0x3FFF.
									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	1C	XTALIN	Input	N/A	Crystal Input. Connect this signal to a 24-MHz
									parallel-resonant, fundamental mode crystal and load
									capacitor to GND.
									It is also correct to drive XTALIN with an external
									24-MHz square wave derived from another clock
									source. When driving from an external source, the
									driving signal should be a 3.3V square wave.
11		10	11	4	2C	XTALOUT	Output	N/A	Crystal Output. Connect this signal to a 24-MHz
									parallel-resonant, fundamental mode crystal and load
									capacitor to GND.
									If an external clock is used to drive XTALIN, leave this
									pin open.
1		100	5	54	2B	CLKOUT on	O/Z	12 MHz	CLKOUT: 12-, 24- or 48-MHz clock, phase locked to the
						CY7C68013A			24-MHz input clock. The 8051 defaults to 12-MHz
						and			operation. The 8051 may three-state this output by
						CY7C68014A			setting CPUCS.1 = 1.
						------------------	-----------	----------	------------------------------------------------------------------------
						PE1 on	IO/Z	I	PE1 is a bidirectional IO port pin.

Port	A
82		67	40	33	8G	PA0 or	IO/Z	I	Multiplexed pin whose function is selected by
						INT0#		(PA0)	PORTACFG.0
									PA0 is a bidirectional IO port pin.
									INT0# is the active-LOW 8051 INT0 interrupt input
									signal, which is either edge triggered (IT0 = 1) or level
									triggered (IT0 = 0).
83		68	41	34	6G	PA1 or	IO/Z	I	Multiplexed pin whose function is selected by:
						INT1#		(PA1)	PORTACFG.1
									PA1 is a bidirectional IO port pin.
									INT1# is the active-LOW 8051 INT1 interrupt input
									signal, which is either edge triggered (IT1 = 1) or level
									triggered (IT1 = 0).
84		69	42	35	8F	PA2 or	IO/Z	I	Multiplexed pin whose function is selected by two bits:
						SLOE or		(PA2)	IFCONFIG[1:0].
									PA2 is a bidirectional IO port pin.
									SLOE is an input-only output enable with program-
									mable polarity (FIFOPINPOLAR.4) for the slave FIFOs
									connected to FD[7..0] or FD[15..0].
