format  Uint32 * CDC_GetDataPtr (void)
 Input  None
 Output  None
 Function value  Register pointer (address value)
 Function  Gets the data transfer register (DATATRNS) pointer. 

   (1) Access method 
.  The following three types of data transfer methods are available for data transfer registers and MPEG registers.
 There is .
 DMA  · DMA transfer by SCU
 DMA  -DMA transfer by CPU
 Software transfer by CPU 
:  Registers are accessed in longword (32 bits) for DMA transfer and software transfer by the CPU.
 Must be . In other words, the data to be transferred is in units of long words (even words).
. 
 Data  The data accessed by longword is stored in order of upper word and lower word. Odd number
When transferring  data, the lower word of the last longword access is undefined. 

   (2) Volatile declaration 
  When assigning a pointer to a variable, a volatile declaration is required to prevent unauthorized optimization. 

 Example  volatile Uint32 * ptr;
:  ptr = CDC_GetDataPtr (); 

 format  Sint32 CDC_GetHirqReq (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 factor register (HIRQREQ).
