EPROM/OTPROM (PROM)
To program the PROM MCU, the MCU is installed in the PCB, along with
an EPROM device programmed with user code; the MCU is then
subjected to a series of routines. The routines necessary to program,
verify, and secure the PROM MCU are:
Other board routines available to the user are:
The user first configures the MCU for the bootstrap mode of operations
by installing a fabricated jumper across pins 1 and 2 of the board’s mode
select header, J1. Next, the board’s mode switches (S3, S4, S5, and S6)
are set to determine the routine to be executed after the next reset, as
shown in
