format  void SYS_CHGSCUIM (Uint32 AndMask, Uint32 OrMask);
 Input  AndMask: Mask value for permission
:  OrMask: Mask value for rejection
 Output  None
 No function value 
 Function  Mask storage memory contents are ANDed with AndMask and ORed with Or-Mask.
  Writes to the disk storage memory and SCU interrupt mask register. Next, the logic of AndMask and OrMask
Write  sum  to the SCU status register. However, the A-Bus interrupt mask bit is enabled
In case of  , the upper word of the status register is cleared, and the A-Bus interrupt acknowledge register
 Clear . Perform these operations atomically.
 Remarks  This routine must not be used from interrupt processing (for SCU interrupts)
  SYS_GETSCUIM value is undefined.)
  If an SCU interrupt occurs during processing, the interrupt may disappear (SCU specification). Its possible
  Use it in a situation where you avoid the ability or do not know.
  If this routine is called on slave SH2, the results are not guaranteed.

 Function value  Mask save memory value
 Function  Reads the value of the mask storage memory. This value is set / changed in the SCU interrupt mask register.
If   is performed with the above function, it is the same as the value actually set in the SCU interrupt mask register.
 Remarks  During SCU interrupt processing, the application uses SYS_SETSCUIM () and SYS_CHGSCUIM () to set
The mask value for each interrupt factor (if the application uses SYS_CHGUIPR () as the value of . 
 The corresponding value in the table of  changes to a logical sum. However, when interrupts are multiplexed, the argument is further increased.
 Changes  Riwa.
  Therefore, this value is undefined during SCU interrupt processing. Processing that depends on the referenced value during processing
Do not  .
