6.4.1 Dividend Register (MMDVSQ_DEND)
This register is loaded with the input dividend operand before a divide operation is
initiated. The register is updated by the MMDVSQ hardware during the execution of a
divide or square root calculation. Any memory access (read or write) of the DEND
register while the module is busy during a calculation causes the access to be stalled
(using wait states) until the calculation completes.

DIVIDEND
Dividend
This is the input dividend operand for divide calculations.
6.4.2 Divisor Register (MMDVSQ_DSOR)
This register is loaded with the input divisor operand before a divide operation is
initiated. If CSR[DFS] = 0, a write to this register inititates a divide operation. Any
memory access (read or write) of the DSOR register while the module is busy during a
calculation causes the access to be stalled (using wait states) until the calculation
completes.
