Section 6 Instruction Descriptions
6.3.4
Format
PADDC Sx,
Sy, Dz
Description: Adds the contents of the Sx and Sy operands to the DC bit and stores the result in the
Dz operand. The DC bit of the DSR register is updated as the carry flag. The N, Z, V, and GT bits
of the DSR register are also updated.
Note: The DC bit is updated as the carry flag after execution of the PADDC instruction
