Power-on reset request
Exception code H'000 is set in EXPEVT, initialization of the CPU and on-chip peripheral
module is carried out, and then a branch is made to the reset vector (H'A0000000). For details,
see the register descriptions in the relevant sections. A power-on reset should be executed
when power is supplied.
Manual reset request
Exception code H'020 is set in EXPEVT, initialization of the CPU and on-chip peripheral
module is carried out, and then a branch is made to the branch vector (H'A0000000). The
registers initialized by a power-on reset and manual reset are different. For details, see the
register descriptions in the relevant sections.
Exception code H'000 is set in EXPEVT, initialization of VBR and SR is performed, and a
branch is made to PC = H'A0000000.
CPU and on-chip peripheral module initialization is performed. For details, see the register
descriptions in the relevant sections.
