; specifying the address to start loading the program words and then 3 bytes
; forming 24-bit words for each program word to be loaded.
; The program words will be stored in contiguous PRAM memory locations
; starting at the specified starting address.
; After reading the program words, program execution starts from the same
; address where loading started.
; The Host Interface bootstrap load program may be stopped by setting the
; Host Flag 0 (HF0). This will start execution of the loaded program from
; the specified starting address.
;
; The base address of the HI08 in multiplexed mode is 0x80 and is not
; modified by the bootstrap code. All the address lines are enabled
; and should be connected accordingly.

; If MD:MC:MB:MA=1111, then it loads the program RAM from the Host
; Interface programmed to operate in the MC68302 (IMP) bus mode,
; in single-strob pin configuration.
; The HOST MC68302 bootstrap code expects accesses that are byte wide.
; The HOST MC68302 bootstrap code expects to read 3 bytes forming a 24-bit word
; specifying the number of program words, 3 bytes forming a 24-bit word
; specifying the address to start loading the program words and then 3 bytes
; forming 24-bit words for each program word to be loaded.
; The program words will be stored in contiguous PRAM memory locations
; starting at the specified starting address.

; The Host Interface bootstrap load program may be stopped by setting the
