MAC0HO: Hard Overflow Flag.
This bit is set to ‘1’ whenever an overflow out of the MAC0OVR register occurs during a
MAC operation (i.e. when MAC0OVR changes from 0x7F to 0x80 or from 0x80 to 0x7F).
The hard overflow flag must be cleared in software by directly writing it to ‘0’, or by resetting
the MAC logic using the MAC0CA bit in register MAC0CF.
MAC0Z: Zero Flag.
This bit is set to ‘1’ if a MAC0 operation results in an Accumulator value of zero. If the result
is non-zero, this bit will be cleared to ‘0’.
MAC0SO: Soft Overflow Flag.
This bit is set to ‘1’ when a MAC operation causes an overflow into the sign bit (bit 31) of the
MAC0 Accumulator. If the overflow condition is corrected after a subsequent MAC operation,
this bit is cleared to ‘0’.
MAC0N: Negative Flag.
If the MAC Accumulator result is negative, this bit will be set to ‘1’. If the result is positive or
zero, this flag will be cleared to ‘0’.
The contents of this register should not be changed by software during the first two MAC0 pipeline
stages.
