| ** will be correct if we change the loadbase for the code. Which |
| ** brings us onto another issue - the loadbase is the *end* of the |
| ** code, not the start. |
| ** |
| ** If I were you I wouldn't start from here. |
| */ |
| |
| /* |
| ** We now need to insert a short boot section into |
| ** the memory at the end of Sram2. This is normally (de)composed |
| ** of the last eight bytes of the download code. The |
| ** download has been assembled/compiled to expect to be |
| ** loaded from 0x7FFF downwards. We have loaded it |
| ** at some other address. The startup code goes into the small |
| ** ram window at Sram2, in the last 8 bytes, which are really |
| ** at addresses 0x7FF8-0x7FFF. |
| ** |
| ** If the loadbase is, say, 0x7C00, then we need to branch to |
| ** address 0x7BFE to run the host.bin startup code. We assemble |
| ** this jump manually. |
| ** |
| ** The two byte sequence 60 08 is loaded into memory at address |
| ** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0, |
| ** which adds '0' to the .O register, complements .O, and then shifts |
| ** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will |
| ** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new |
| ** location. Now, the branch starts from the value of .PC (or .IP or |
| ** whatever the bloody register is called on this chip), and the .PC |
| ** will be pointing to the location AFTER the branch, in this case |
| ** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8. |
| ** |
| ** A long branch is coded at 0x7FF8. This consists of loading a four |
| ** byte offset into .O using nfix (as above) and pfix operators. The |
| ** pfix operates in exactly the same way as the nfix operator, but |
| ** without the complement operation. The offset, of course, must be |
| ** relative to the address of the byte AFTER the branch instruction, |
| ** which will be (urm) 0x7FFC, so, our final destination of the branch |
| ** (loadbase-2), has to be reached from here. Imagine that the loadbase |
| ** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which |
| ** is the first byte of the initial two byte short local branch of the |
| ** download code). |
| ** |
| ** To code a jump from 0x7FFC (which is where the branch will start |
| ** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)= |
| ** 0x7BFE. |
| ** This will be coded as four bytes: |
| ** 60 2C 20 02 |
| ** being nfix .O+0 |
| ** pfix .O+C |
| ** pfix .O+0 |
| ** jump .O+2 |
| ** |
| ** The nfix operator is used, so that the startup code will be |
| ** compatible with the whole Tp family. (lies, damn lies, it'll never |
| ** work in a month of Sundays). |
| ** |
| ** The nfix nyble is the 1s complement of the nyble value you |
| ** want to load - in this case we wanted 'F' so we nfix loaded '0'. |
