◆ EXPTBL

volatile uint8_t EXPTBL[4]
static

MSX Expansion flags for each primary slots.

The bit #7 of EXPTBL[i] indicates whether the primary slot #i is expanded or not. If the bit #7 was 1, the primary slot #i is expanded to 4 secondary slots. Otherwise, the primary slot #i is single slot.

And the EXPTBL[0] is also indicates actual MAIN ROM slot address. For any other EXPTBL[i], only bit #7 is used.

A slot address (or 'slot' in short) is a 8 bit value consists of the following:

  • bit #7 : expanded (1) or not (0)
  • bit #6..#4 : unused
  • bit #3..#2 : secondary slot number (0..3) if bit #7 was 1

  • bit #7..#6 : secondary slot number of page #3
  • bit #5..#4 : secondary slot number of page #2
  • bit #3..#2 : secondary slot number of page #1
  • bit #1..#0 : secondary slot number of page #0

Definition at line 290 of file workarea.h.

◆ SLTATR

volatile uint8_t SLTATR[64]
static

MSX Attributes for application (cartridge).

For each slot, indicates which pages contain or do not contain MSX-BASIC program text, MSX-BASIC extended device routines, and/or MSX-BASIC extended statements.

There is 1 byte for each page of each slots. For page #p of slot #m-n, SLTATR[i] is used where i = 16*m + 4*n + p.

SLTATR[*] corresponding page/slot
SLTATR[ 0] for page #0 of slot #0-0
SLTATR[ 2] for page #1 of slot #0-0
... ...
SLTATR[62] for page #2 of slot #3-3
SLTATR[63] for page #3 of slot #3-3

Each SLTATR[i] is a 8 bit value consists of the following:

  • bit #7 : MSX-BASIC program TEXT exists (1), or not (0)
  • bit #6 : MSX-BASIC extended DEVICE routine exists (1), or not (0)
  • bit #5 : MSX-BASIC extended STATEMENT exists (1), or not (0)
  • bit #4..#0 : unused

Definition at line 316 of file workarea.h.
