(1) Multiplication/division data register A (MDAH, MDAL)
Symbol
Symbol
The MDAH and MDAL registers set the values that are used for a multiplication or division operation and store the
operation result. They set the multiplier and multiplicand data in the multiplication mode, and set the dividend data
in the division mode. Furthermore, the operation result (quotient) is stored in the MDAH and MDAL registers in the
division mode.
The MDAH and MDAL registers can be set by a 16-bit manipulation instruction.
Reset signal generation clears these registers to 0000H.
Cautions 1. Do not rewrite the MDAH and MDAL registers values during division operation processing
The following table shows the functions of the MDAH and MDAL registers during operation execution.
