Exception Handling Functions 

5.3.1 

Exception Handling Flow 

In exception handling, the contents of the program counter (PC), status register (SR), and R15 are 
saved in the saved program counter (SPC), saved status register (SSR), and saved general 
register15 (SGR), and the CPU starts execution of the appropriate exception handling routine 
according to the vector address. An exception handling routine is a program written by the user to 
handle a specific exception. The exception handling routine is terminated and control returned to 
the original program by executing a return-from-exception instruction (RTE). This instruction 
restores the PC and SR contents and returns control to the normal processing routine at the point at 
which the exception occurred. The SGR contents are not written back to R15 with an RTE 
instruction. 

The basic processing flow is as follows. For the meaning of the SR bits, see section 2, 
Programming Model. 

1.  The PC, SR, and R15 contents are saved in SPC, SSR, and SGR, respectively. 

2.  The block bit (BL) in SR is set to 1. 

3.  The mode bit (MD) in SR is set to 1. 

4.  The register bank bit (RB) in SR is set to 1. 

5.  In a reset, the FPU disable bit (FD) in SR is cleared to 0. 

6.  The exception code is written to bits 11 to 0 of the exception event register (EXPEVT) or 

interrupt event register (INTEVT). 

7.  The CPU branches to the determined exception handling vector address, and the exception 

handling routine begins. 

 

5.3.2 

Exception Handling Vector Addresses 

The reset vector address is fixed at H'A0000000. Exception and interrupt vector addresses are 
determined by adding the offset for the specific event to the vector base address, which is set by 
software in the vector base register (VBR). In the case of the TLB miss exception, for example, 
the offset is H'00000400, so if H'9C080000 is set in VBR, the exception handling vector address 
will be H'9C080400. If a further exception occurs at the exception handling vector address, a 
duplicate exception will result, and recovery will be difficult; therefore, addresses that are not to 
be converted (in P1 and P2 areas) should be specified for vector addresses.
