⎯ SCK2 pin low level and RESET pin low level
⎯ When a general exception other than a user break occurs while the BL bit is set to 1 in SR
⎯ When the watchdog timer overflows while the WT/IT bit and RSTS bit are both set to 1 in
Exception code H'020 is set in EXPEVT, initialization of VBR and SR is performed, and a
branch is made to PC = H'A000 0000.
In the initialization processing, the VBR register is set to H'0000 0000, and in SR, the MD,
RB, and BL bits are set to 1, the FD bit is cleared to 0, and the interrupt mask bits (IMASK)
are set to B'1111.
CPU and on-chip peripheral module initialization is performed. For details, see the register
descriptions in the relevant sections.
