Along with its on-board programming mode, this LSI also has a programmer mode as another
mode for programming/erasing of programs and data. In programmer mode, a general PROM
programmer that supports Renesas microcomputers with 512-Kbyte flash memory as a device
type*
on the user MAT and user boot MAT*
A status-polling system is adopted for operation in automatic programming, automatic erasure,
and status-read modes. In status-read mode, details of the internal signals are output after
execution of automatic programming or automatic erasure. In programmer mode, a 12-MHz clock
signal must be input.
Notes: 1. In this LSI, set the programming voltage of the PROM programmer to 3.3 V.
