5 The SX-Key Debugger
Registers $10 through $1F of all other banks are shown in the columns on the far right of the window.
The bank offsets are labeled at the top of each column and the current bank is highlighted in white.
These columns will expand or contract to fit the number of RAM banks available in the SX. In this
example, eight banks are shown.
The blue outline, shown here on the IND register, indicates the location that the FSR (file select register)
is currently pointing at.
The second column, just to the right of the first sixteen registers, displays a binary representation of
some of the registers, namely IND, Status, RA, RB, RC and 08 through 0F.
At the top center of the Registers window are the contents of the M register (hexadecimal) and the W
register (both hexadecimal and binary) and the Interrupt and Skip flags. The Interrupt and Skip flags
turn blue when set and white when cleared. The interrupt flag is set when an interrupt has occurred
and cleared after the interrupt has been serviced. The Skip flag is set when the compare condition
evaluates to true, i.e. when the skip will be performed. It is cleared when the condition evaluates to
false, or after the skip has been performed.
