Section 5 Exception Handling
5.5.2
When an address error occurs, address error exception handling starts after the bus cycle causing
the address error ends and current instruction execution completes. The address error exception
handling is as follows:
1. The contents of PC, CCR, and EXR are saved in the stack.
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. An exception handling vector table address corresponding to the address error is generated, the
Even though an address error occurs during a transition to an address error exception handling, the
address error is not accepted. This prevents an address error from occurring due to stacking for
exception handling, thereby preventing infinitive stacking.
If the SP contents are not a multiple of 2 when an address error exception handling occurs, the
stacked values (PC, CCR, and EXR) are undefined.
When an address error occurs, the following is performed to halt the DTC and DMAC.
• The ERR bit of DTCCR in the DTC is set to 1.
• The ERRF bit of DMDR_0 in the DMAC is set to 1.
• The DTE bits of DMDRs for all channels in the DMAC are cleared to 0 to forcibly terminate
Table 5.6 shows the state of CCR and EXR after execution of the address error exception
handling.
