ALE

XTAL1

Address Latch Enable output for latching the low byte of

the address during accesses to external memory. ALE is

activated as though for this purpose at a constant rate of

1/6 the oscillator frequency except during an external

data memory access at which time one ALE pulse is

skipped. ALE can sink or source 8 LS TTL inputs. It can

drive CMOS inputs without an external pullup.

Input to the inverting amplifier that forms the oscillator.

Receives the external oscillator signal when an external

oscillator is used.

XTAL2

Output of the inverting amplifier that forms the oscillator,

and input to the internal clock generator. This pin should

be floated when an external oscillator is used.

PSEN

Program Store Enable output is the read strobe to external

Program Memory. PSEN is activated twice each machine

cycle during fetches from external Program Memory.

(However, when executing out of external Program

Memory, two activations of PSEN are skipped during

each access to external Data Memory). PSEN is not

activated during fetches from internal Program Memory.

PSEN can sink/source 8 LS TTL inputs. It can drive

CMOS inputs without an external pullup.

When EA is held high, the CPU executed out of internal

Program Memory (unless the Program Counter exceeds

3FFFH). When EA is held low, the CPU executes only out

of external Program Memory. EA must not be floated.

Idle and Power Down Operation

Figure 3 shows the internal Idle and Power Down clock

configuration. As illustrated, Power Down operation

stops the oscillator. The interrupt, serial port, and timer

blocks continue to function only with external clock

(INT0, INT1, T0, T1).

Idle Mode operation allows the interrupt, serial port, and

timer blocks to continue to function with internal or

external clocks, while the clock to CPU is gated off. The

special modes are activated by software via the Special

Function Register, PCON. Its hardware address is 87H.

PCON is not bit addressable.
