If Index Register IX contains 2000h and bit 6 in memory location 2004h contains 1, then
upon the execution of a BIT 6, (IX+ 4h ) instruction, the Z flag in the F Register contains a
0 and bit 6 in memory location 2004h still contains a 1. Bit 0 in memory location 2004h
is the least-significant bit.
