P3.4 T0 (timer 0 outside input)
P3.5 T1 (timer 1 outside input)
P3.6/WR (external data memory write gate)
P3.7/RD (external data memory read gate)
The P3 mouth is flicker programming and programming verification reception number control signal simultaneously.
RST: input resets.When the oscillator reset device, keep the RST pin high level time of two machine cycles.
ALE/PROG: when access external memory, the output level that address latch allows is used for the ground bit byte of latch address.During the FLASH programming, this pin is used to import programming pulse.At ordinary times, the ALE end is with constant frequency period output positive pulse signal, and this frequency is 1/6 of an oscillator frequency.Therefore it can be used as the pulse that the outside is exported or is used for regularly purpose.
/ PSEN: the gating signal of external program memory.During getting finger by external program memory, each machine cycle, twice/PSEN was effective.But when the access external data storer, this twice effective/PSEN signal will not occur.
/ EA/VPP: when/EA kept low level, whether external program memory (0000H-FFFFH) during this period then was no matter there is internal program memory.When noting cipher mode 1 ,/EA is RESET with internal lock; When/EA end keeps high level, internal program memory around here.During the FLASH programming, this pin also is used to apply 12V programming power supply (VPP).
XTAL1: the input of reverse monofier and the input of internal clocking operating circuit.
XTAL2: the output that comes the self-reversal oscillator.
