(3) Multiplication/division data register C (MDCL, MDCH)
The MDCH and MDCL registers store remainder value of the operation result in the division mode. They are not
used in the multiplication mode.
The MDCH and MDCL registers can be read by a 16-bit manipulation instruction.
Reset signal generation clears these registers to 0000H.
Caution The MDCH and MDCL registers values read during division operation processing (while the
Remark
The register configuration differs between when multiplication is executed and when division is executed, as follows.
• Register configuration during multiplication
• Register configuration during division
