The two RMB-166 headers, the input output port header JP2 and the system header JP1, are simil ar to the headers JP6 and JP7 of the RM B-167. In addition, the RM B-167 has JP8, the Extra Input/Out[...]

Jumpers JP4 and JP5 sel ect the source of re[...]

- - 21 8 BOOTSTRAPPING The RMB-167 bootstr apping is tri ggered by grounding P0L.4 at r eset. A 16 pin header is used to ground the bits of P0L via a r esistor arr ay with a nomi nal value in the range of 22K to 33K. Note that the GAL which contr ols the bootstrap load oper ation is also r esponsible for tur ning on the LED. In its default i mpleme[...]

- - 22 Note that the NOP (no operation) operations are required to fill the 32 bytes, since the bootstrap loader rem ains active until al l 32 bytes are recei ved. When the bootstrap l oader receives i ts last byte and places it in addr ess 0FA5Fh, it makes a jump to 0FA40h and star ts executing the code. This is the shor t loop given above. Note t[...]

- - 23 respectively. The code w ithin the 604-byte dow nload block pokes these bytes starti ng from address 0. That is, these instr uctions are placed i nto memory, one w ord at a time, as data. The following i nstructions are used. mov R1, #0A55Ah ; begin: DISWDT mov 0, R1 mov R1, #0A5A5h mov 2, R1 mov R1, #0B54Ah ; EINIT mov 4, R1 mov R1, #0B5B5h[...]

- - 24 9 THE MINIMAL MONITOR The minim al monitor is placed by the bootstrap l oader starting at addr ess 8000h. The monitor responds to two single- letter comm ands ’ D’ and ’G’ . The ’ D’ command places the monitor in a download mode. C ode in the Intel Hex form at is expected. Code may be dow nloaded anywhere in the first 64L segm en[...]

- - 25 9.1 MON167 Monitor The monitor pr ogram RM ON167 allow s inspecting and modi fying the first 64K segm ent of RMB- 167 memory, confi guring the ports, i nputting and outputting from the general purpose por ts, downloading code in the Intel Hex format, and br anching to user code. RM ON167 features are invoked by single-letter commands. RMON16[...]

- - 26 P Port Data The P command is used to r ead from or write to the por ts. Pn displays the curr ent value of port n. If port n is an input por t, then the value read is the current voltage l evels applied to the por ts. If port n is an o u tput port, Pn re turns the curre n t output va lue to port n. P n =mmmm sets the curren t value of output [...]
