11. Initialization
In the device, there are internal registers which is initialized only by a power-on reset. To initialize these registers
turning on the power again.
12. Return from standby state
If the power-supply voltage goes below the standby RAM holding voltage in the standby state, the device may
fail to return from the standby state. In this case, reset the device via the external reset pin to return to the normal
state.
13. 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 corre-
sponding 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,’ the remainder obtained after the execution of the instruction
will not be placed in the instruction operand register.
14. Using of REALOS
The use of EI
2
OS is not possible the REALOS real time operating system.
