4 / 16 page  AT87LV51 4 PSEN Program Store Enable is the read strobe to external pro- gram memory. When the AT87LV51 is executing code from external pro- gram memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. EA/VPP External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external pro- gram memory locations starting at 0000H, up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. This pin also receives the 12-volt programming enable volt- age (VPP) during QuickFlash programming. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2 Output from the inverting oscillator amplifier. Special Function Registers A map of the on-chip memory area called the Special Func- tion Register (SFR) space is shown in Table 1. Table 1.
