DESCRIPTION
The 4519 Group is a 4-bit single-chip microcomputer designed with
CMOS technology. Its CPU is that of the 4500 series using a
simple, high-speed instruction set. The computer is equipped with
serial I/O, four 8-bit timers (each timer has one or two reload regis-
ter), a 10-bit A-D converter, interrupts, and oscillation circuit switch
function.
The various microcomputers in the 4519 Group include variations
of the built-in memory size as shown in the table below.

This pin is used to operate/stop the voltage drop detection circuit. When "H" level is
input to this pin, the circuit starts operating. When "L" level is input to this pin, the
circuit stops operating.
An N-channel open-drain I/O pin for a system reset. When the SRST instruction,
watchdog timer or the voltage drop detection circuit cause the system to be reset,
the
RESET
pin outputs "L" level.
I/O pins of the main clock generating circuit. When using a ceramic resonator, connect
it between pins X

. When using a 32 kHz quartz-crystal oscillator, connect it
between pins X
