 Function  Registers the interrupt function address to the interrupt vector indicated by the vector number. Registered interrupt
The  function  is executed when an interrupt occurs. If the interrupt function address is NULL, a vector
The function registered in the interrupt vector according to the contents of .  number is as follows.
 
 
 
 If the vector number is SCU: Reregister the SCU interrupt function.
 If the vector number is not SCU: Register a dummy function. Dummy function returns
This is a function that performs only processing. 
 Remarks  The interrupt functions that can be specified are functions that end with register save, return, and RTE instructions (in C language)
:  You can specify a function that uses the #pragma interrupt declaration).
 This function can be used for both master and slave SH2. Execute this function on the CPU you want to register
