(13) Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers,
please turn on the power again.
(14) Directions of “DIV A, Ri” and “DIVW A, RWi” instructions
In the Signed multiplication and division instructions (“DIV A, Ri” and “DIVW A, RWi”) , the value of the corre-
sponding bank register (DTB, ADB, USB, SSB) is set in “00h”.
If the values of the corresponding bank registers (DTB, ADB, USB, SSB) are set to other than “00h”, the remainder
by the execution result of the instruction is not stored in the register of the instruction operand.
(15) Using REALOS
The use of EI2OS is not possible with the REALOS real time operating system.
Oscillation setting time*2
Power-on reset*1
VCC (Power-supply pin)
PONR (power-on reset) signal
RST (external asynchronous reset) signal
RST (internal reset) signal
Oscillation clock signal
KA (internal operation clock A) signal
KB (internal operation clock B) signal
PORT (port output) signal
High-impedance
*1 : Power-on reset time : Period of “clock frequency
× 217” (Clock frequency of 16 MHz : 8.19 ms)
*2 : Oscillation setting time : Period of “clock frequency
× 218” (Clock frequency of 16 MHz : 16.38 ms)
RST pin is “L”
