The ZDI BREAK on the next CPU instruction is disabled.
Clearing this bit releases the CPU from its current BREAK
condition.
The ZDI BREAK on the next CPU instruction is enabled.
The CPU can use multibyte Op Codes and multibyte
operands. BREAK points only occur on the first Op Code in
a multibyte Op Code instruction. If the ZCL pin is High and
the ZDA pin is Low at the end of RESET, this bit is set to 1
and a BREAK occurs on the first instruction following the
RESET. This bit is set automatically during ZDI BREAK on
address match. A BREAK can also be forced by writing a 1
to this bit.
The ZDI BREAK, upon matching BREAK address 3, is
disabled.
The ZDI BREAK, upon matching BREAK address 3, is
enabled.
The ZDI BREAK, upon matching BREAK address 2, is
disabled.
The ZDI BREAK, upon matching BREAK address 2, is
enabled.
The ZDI BREAK, upon matching BREAK address 1, is
disabled.
The ZDI BREAK, upon matching BREAK address 1, is
enabled.
The ZDI BREAK, upon matching BREAK address 0, is
disabled.
The ZDI BREAK, upon matching BREAK address 0, is
enabled.
