SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER for INFRARED REMOTE CONTROL TRANSMITTERS
(1) PROM mode (serial input/output)
The M34280E1FP/GP has a PROM mode in addition to a
normal operation mode. It has a function to serially input/output
the command codes, addresses, and data required for
operation (e.g., read and program) on the built-in PROM using
only a few pins. This mode can be selected by setting pins
SDA (serial data input/output), SCLK (serial clock input), PGM
and V
PP
to “H” after connecting wires as shown in Figure 1
and powering on the V
DD
pin, and then applying 12.5V to the
V
PP
pin.
In the PROM mode, three types of software commands (read,
program, and program verify) can be used. Clock-synchronous
serial I/O is used, beginning from the LSB (LSB first).
Refer to the Mitsubishi Data Book “DEVELOPMENT
SUPPORT TOOLS FOR MICROCOMPUTERS” about the
serial programmer for the Mitsubishi single-chip
microcomputers.
