The various exception handling operations explained here are exception sources, transition address
on the occurrence of exception, and processor operation when a transition is made.
5.6.1 Resets
(1) Power-On
Reset
•
Condition:
Power-on reset request
•
Operations:
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.
(2) Manual
Reset
•
Condition:
Manual reset request
•
Operations:
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.
(3) H-UDI
Reset
•
Source: SDIR.TI[7:4] = B'0110 (negation) or B'0111 (assertion)
•
Transition address: H'A0000000
•
Transition operations:
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.
