ADDRA and ADDRB buffer operation:
conversion result → ADDRA → ADDRB
ADDRA and ADDRC, also ADDRB and ADDRD buffer
operation:
conversion result 1 → ADDRA → ADDRC, conversion
result 2 → ADDRB → ADDRD (ADDRC and ADDRD are
buffer registers)
ADDRA to ADDRD buffer operation:
conversion result → ADDRA → ADDRB → ADDRC →
ADDRD (ADDRB to ADDRD are buffer registers)
