TMS1000 family - TMS1400, TMS1470, TMS1475, TMS1600, TMS1670
TMS1400 follows the TMS1100, it doubles the ROM size again (4 chapters of 16 pages), and adds a 3-level callstack
- rotate the view and mirror the OR-mask to get the proper layout of the mpla, the default is identical to tms1100
- rotate the view and mirror the OR-mask to get the proper layout of the mpla, the default is identical to TMS1100
- the opla size is increased from 20 to 32 terms
TMS1475 adds more R pins (indexed from X MSB)
- opla OR order appears to be flipped: O7-O0
TMS1600 adds more I/O to the TMS1400, input pins are doubled with added L1,2,4,8
- rotate the view and mirror the OR-mask to get the proper layout of the mpla, the default is identical to tms1100
- the opla size is increased from 20 to 32 terms
- mpla and opla are the same as TMS1400
TODO:
- emulate TMS1600 L-pins
