Half-Carry Flag
From SnesLab
(Redirected from Half-carry flag)
The Half-carry flag (H) exists on the SPC700, as bit 3 of the Program Status Word. It applies to the bottom 4 bits of the accumulator, meaning it is set whenever bit 3 of an ALU operation carries over into bit 4.
It is cleared by CLRV, but there is no SETV command to set it.
