DESCRIPTION
NAME
44
PSEN
OSCCLK
MODCLK
Program Store Enable: Connected to optional external memory as a chip enable. PSEN will provide an active low pulse.
In programming mode, PSEN is used as an input along with ALE to define serial or parallel programming mode.
PSEN is held high for parallel programming and held low for serial programming. This pin can also be selected (when not
using external memory) to output the Oscillator clock, Modulator clock, high, or low. Care should be taken so that loading
on this pin should not inadvertently cause the device to enter programming mode.

ALE
Address Latch Enable: Used for latching the low byte of the address during an access to external memory. ALE is emitted at
a constant rate of 1/4 the oscillator frequency, and can be used for external timing or clocking. One ALE pulse is skipped
during each access to external data memory. In programming mode, ALE is used as an input along with PSEN to define
serial or parallel programming mode. ALE is held high for serial programming and held low for parallel programming. This pin
can also be selected (when not using external memory) to output high or low. Care should be taken so that loading on this
pin should not inadvertently cause the device to enter programming mode.
48
EA
External Access Enable: EA must be externally held low to enable the device to fetch code from external program
memory locations starting with 0000h. No internal pull-up on this pin.
