NAME AND FUNCTION
PSEN

O
Program Store Enable:
The read strobe to external program memory. When executing
code from the external program memory, PSEN is activated twice each machine cycle,
except that two PSEN activations are skipped during each access to external data memory.
PSEN is not activated during fetches from internal program memory.

External Access Enable/Programming Supply Voltage:
EA must be externally held low
to enable the device to fetch code from external program memory locations starting with
0000H. If EA is held high, the device executes from internal program memory unless the
program counter contains an address greater than 8k Devices (IFFFH), 16k Devices
(3FFFH) or 32k Devices (7FFFH). Since the RD+ has 64k Internal Memory, the RD+ will
execute only from internal memory when EA is held high. This pin also receives the 12.75V
programming supply voltage (V
PP
) during EPROM programming. If security bit 1 is
programmed, EA will be internally latched on Reset.

Crystal 1:
Input to the inverting oscillator amplifier and input to the internal clock generator
circuits.

Crystal 2:
Output from the inverting oscillator amplifier.
NOTE:
To avoid “l(fā)atch-up” effect at power-on, the voltage on any pin at any time must not be higher than V
CC
+ 0.5V or V
SS
– 0.5V, respectively.
