Indeterminate outputs from ports 0 and 1
The outputs from ports 0 and 1 become indeterminate during oscillation setting time of step-down circuit (during
a power-on reset) after the power is turned on.
Pay attention to the port output timing shown as follow
13.Initialization
The device contains internal registers that can be initialized only by a power-on reset. To initialize the internal
registers, restart the power supply.
14. Interrupt Recovery from Standby
If an external interrupt is used for recovery from standby, use an “H” level input request. An “L” level request
causes abnormal operation.
15.Precautions for Use of
DIV A, Ri
, and
DIVW A, Ri
Instructions
The signed multiplication-division instructions “DIV A, Ri”, and “DIVW A, RWi” should be used when the
corresponding bank registers (DTB, ADB, USB, SSB) are set to value “00h”. If the corresponding bank registers
(DTB, ADB, USB, SSB) are set to a value other than “00h,” then the remainder obtained after the execution of
the instruction will not be placed in the instruction operand register.

Extended intelligent I/O service(EI

OS) cannot be used, when REALOS is used.
