format  void CDC_ClrHirqReq (Sint32 bitpat)
 Input  bitpat: Clear bit pattern (Set the bit you want to clear to 0 and the others to 1)
 Output  None
 Function value  None
 Function  Clears the interrupt factor register according to the specified bit pattern.
 Remarks  The CMOK flag in the interrupt factor register is used by the CD communication interface.
 Clearing by  program is prohibited.
  The DCHG flag is cleared by BOOT ROM when the disk is checked.
 Do not clear when initializing  grams. (Can be cleared only when DCHG interrupt is handled as an exception) 

 format  Sint32 CDC_GetHirqMsk (void)
 Input  None
 Output  None
 function value  register value …… For the bit name, refer to the data specification (Constant)
 Function  Gets the value of the interrupt mask register (HIRQMSK). 

 format  void CDC_SetHirqMsk (Sint32 bitpat)
 Input  bitpat: Mask bit pattern (bits to be masked are 0, others are 1)
 Output  None
 Function value  None
 Function  Sets the interrupt mask register according to the specified bit pattern. 

 format  Uint32 * CDC_GetMpegPtr (void)
 Input  None
 Output  None
 Function value  Register pointer (address value)
 Function  Gets a pointer to the MPEG register (MPEGRGB).
  The MPEG register access method is the same as the data transfer register. Notes etc., data
See  Get  Transfer register pointer (CDC_GetDataPtr).
