Section 4 Exception Processing
4.3.2
An interrupt processing request is accepted on completion of the current instruction. The interrupt
acceptance sequence consists of the following operations:
1. The contents of the PC and SR are saved in SPC and SSR, respectively.
2. The BL bit in SR is set to 1, masking any subsequent exceptions.
3. The MD bit in SR is set to 1 to place the SH7706 in privileged mode.
4. The RB bit in SR is set to 1.
5. An encoded value identifying the exception event is written to bits 11 to 0 of the INTEVT and
6. Instruction execution jumps to the vector location designated by the sum of the value of the
4.3.3
When the SH7706 encounters any exception condition other than a reset or interrupt request, it
executes the following operations:
1. The contents of the PC and SR are saved in the SPC and SSR, respectively.
2. The BL bit in SR is set to 1, masking any subsequent exceptions.
3. The MD bit in SR is set to 1 to place the SH7706 in privileged mode.
4. The RB bit in SR is set to 1.
5. An encoded value identifying the exception event is written to bits 11 to 0 of the EXPEVT
6. Instruction execution jumps to the vector location designated by either the sum of the vector
