CHAPTER  17   MULTIPLIER/DIVIDER 

User’s Manual  U19780EJ2V0UD

 

505

17.3  Register Controlling Multiplier/Divider 

 

The multiplier/divider is controlled by multiplier/divider control register 0 (DMUC0). 

 

(1)   Multiplier/divider control register 0 (DMUC0) 

DMUC0 is an 8-bit register that controls the operation of the multiplier/divider. 

DMUC0 can be set by a 1-bit or 8-bit memory manipulation instruction. 

Reset signal generation clears DMUC0 to 00H.

Note

   When DMUE is set to 1, the operation is started.  DMUE is automatically cleared to 0 after the operation is 

complete. 

 

Cautions  1.   If DMUE is cleared to 0 during operation processing (when DMUE is 1), the operation result 

is not guaranteed.  If the operation is completed while the clearing instruction is being 

executed, the operation result is guaranteed, provided that the interrupt flag is set. 

 

2.   Do not change the value of DMUSEL0 during operation processing (while DMUE is 1).  If it is 

changed, undefined operation results are stored in multiplication/division data register A0 

(MDA0) and remainder data register 0 (SDR0). 

 

3.  If DMUE is cleared to 0 during operation processing (while DMUE is 1), the operation 

processing is stopped.  To execute the operation again, set multiplication/division data 

register A0 (MDA0), multiplication/division data register B0 (MDB0), and multiplier/divider 

control register 0 (DMUC0), and start the operation (by setting DMUE to 1).
