Set to 1 when the divisor is zero; otherwise cleared to 0.
Set to 1 when the quotient is negative; otherwise cleared to 0.
One additional state is required for execution when EXR is valid.
MAC instruction results are indicated in the flags when the STMAC
instruction is executed.
A maximum of three additional states are required for execution of
one of these instructions within three states after execution of a MAC
instruction. For example, if there is a one-state instruction (such as
NOP) between a MAC instruction and one of these instructions, that
instruction will be two states longer.
