rlm@409 148 ;; WRITE
rlm@409 149 ;; JUMP

rlm@377 151 ;;; MODE-SELECT
rlm@377 152 ;; The bootstrap program starts in MODE-SELECT mode.

rlm@377 154 ;; on which buttons are pressed:
rlm@409 155 ;; 0 : MODE-SELECT
rlm@409 156 ;; 0x67 : SET-H
rlm@409 157 ;; 0x6F : SET-L

rlm@409 159 ;; 0xE9 : JUMP
rlm@409 160
rlm@409 161 ;;; SET-H
rlm@409 162 ;; SET-H sets the high 8 bits of the target address to which
rlm@409 163 ;; data will be written / the program will jump. It expects
rlm@409 164 ;; the following:
rlm@409 165 ;;
rlm@409 166 ;; Byte 0 : New Value of H
rlm@409 167 ;; Byte 1 : 0x00
rlm@409 168
rlm@409 169 ;;; SET-L
rlm@409 170 ;; This mode sets the low 8 bits of the target address and has
rlm@409 171 ;; the same semantics as SET-H.
rlm@377 172
rlm@377 173 ;;; WRITE-BYTES
rlm@377 174 ;; WRITE-BYTES mode writes sequences of arbitray values to
rlm@377 175 ;; arbitray memory locations. It expects you to enter a
rlm@409 176 ;; header of one byte describing how many bytes to write.
rlm@377 177
rlm@377 178 ;; Byte 0 : Number of Bytes to Write
rlm@377 179
rlm@377 180 ;; Then, you enter the number of bytes specified in Byte 0
rlm@409 181 ;; and they are written to the start address in sequence.
rlm@409 182 ;; After the last byte is written control returns to
rlm@409 183 ;; MODE-SELECT mode. The Target address will be incremented by
rlm@409 184 ;; Number of Bytes to Write once you are done writing.
rlm@377 185
rlm@377 186 ;; Example: to write the sequence [1 2 3 4] starting at
rlm@409 187 ;; the target address enter:
rlm@377 188 ;; Byte 0 : 4 (will write four bytes)
rlm@377 189 ;; Byte 3 : 1 (write 1 to 0xC01F)
rlm@377 190 ;; Byte 4 : 2 (write 2 to 0xC020)
rlm@377 191 ;; Byte 5 : 3 (write 3 to 0xC021)
rlm@377 192 ;; Byte 6 : 4 (write 4 to 0xC022)
rlm@377 193
rlm@377 194 ;;; JUMP
rlm@409 195 ;; JUMP mode jumps program control to the target address.
rlm@377 196
rlm@409 197 ;;; EXAMPLE
rlm@409 198 ;; To write the infinite loop program [0x18 0xFE] to address
rlm@409 199 ;; 0xC00F and then jump to said program, enter the following
