Operating Modes and On-Chip Memory
4.6.4 Bootloader ROM
4.7 EPROM/OTPROM (M68HC711K4 and M68HC711KS2)
4.7.1 Programming the EPROM with Downloaded Data
Technical Data
90
The bootloader program occupies 512 bytes of bootstrap ROM at
addresses $BE00–$BFFF. It is active only in special modes when the
RBOOT bit in the HPRIO register is set.
The M68HC711K4 devices include 24 Kbytes of on-chip EPROM
(OTPROM in non-windowed packages). The M68HC711KS2 has
32 Kbytes of EPROM.
The two methods available to program the EPROM are:
Before proceeding with programming:
Program the EPROM only at room temperature. Place an opaque label
over the quartz window on windowed parts after programming.
The MCU can download EPROM data through the SCI while in the
special test or bootstrap modes. This can be done either with custom
software, also downloaded through the SCI, or with a built-in utility
program in bootstrap ROM. In either case, the 12-volt nominal
programming voltage must be present on the XIRQ/V
To use the bootstrap ROM utility, download a 3-byte program consisting
of a single jump instruction to $BF00, the starting address of the resident
EPROM programming utility. The utility program sets the X and Y index
