CPU registers
6.3.1
Condition code register (CC)
Reset value: 111x1xxx
The 8-bit Condition Code register contains the interrupt masks and four flags representative
of the result of the instruction just executed. This register can also be handled by the PUSH
and POP instructions.
These bits can be individually tested and/or controlled by specific instructions.
Arithmetic management bits
Bit 4 = H Half carry.
This bit is set by hardware when a carry occurs between bits 3 and 4 of the ALU during
an ADD or ADC instructions. It is reset by hardware during the same instructions.
0: No half carry has occurred.
1: A half carry has occurred.
This bit is tested using the JRH or JRNH instruction. The H bit is useful in BCD
arithmetic subroutines.
