9.3 EPROM/OTPROM (PROM) Programming
The internal PROM can be programmed efficiently using the Motorola
MC68HC05PGMR-2 programmer board, which can be purchased from
a Motorola-authorized distributor. The user can program the
microcontroller unit (MCU) using this printed circuit board (PCB) in
conjunction with an EPROM device already programmed with user code.
Only standalone programming is discussed in this section. For more
information concerning the MC68HC05PGMR and its usages, contact a
local Motorola representative for a copy of the MC68HC05PGMR
Programmer Board User’s Manual #2, Motorola document number
MC68HC05PGMR2/D1.
