Technical Update

SCLL sync output enable is available in I2C bus interface mode only.

a.when the SMi2 bit in the SiC(i=3,4) register = 0(SOUTi output),

The value in the internal RAM area may be rewritten when exiting wait mode if writing to the internal RAM area before entering wait mode.

Program may not operate correctly if an external clock, connected to the XIN pin while the main clock is selected as the CPU clock, is turned off temporarily and then restarted.

When clearing an interrupt request bit of the interrupt control register, depending on the instruction used, an interrupt request bit may not get cleared.

An undefined operation can occur after returning to normal operation mode from a stop mode because an undefined interrupt is generated or, a BRK instruction occurred, etc.

When writing in the internal flash memory via CAN in boot mode, set the mode of CAN transceiver as high-speed mode or normal operation mode.

When the MCU running in low-speed or low power dissipation mode, do not enter WAIT peripheral function clock stop bit set to 1.

If CPU and CAN module attempt to access the SFR at the same time, please note that CPU access to SFR will not synchronize with the CAN module rewrite period.

If performing a read-modify-write sequence of instructions to a register with write only bits, please reset the write only bits to their previous values before writing back to the register.

The interrupts for canceling the WAIT and STOP modes must be enabled before entering either mode. The priority level of the interrupts not used for these modes should be set to 0 before switching into the WAIT or STOP modes.

Wait to change modes until after oscillation has stabilized.

An incorrect interrupt may occur when the request bit of the interrupts is cleared or the interrupt priority level is changed in interrupt enable condition.

When two or more different power sources are supplied to the system, if the input voltage of the unused dedicated input pin is higher than a voltage of Vcc pin, do not connect the dedicated input pin directly to the power source. This will cau

Change of the locking pin position in the magazine (P750PC) used for shipment

Change with the stable supply of trays

Standardization of plastic reel of 330mm in diameter to that complying with the JEITA standards (so-called EIAJ reel).

We will unify the content printed on the inner box for IC trays for the purpose of standardizing our tray packaging specification.

Tray forming die is added in response to the increasing production of LQFP2020 packages, and for through handling in manufacturing factories, new tray type name is adopted.

Change of reel diameter of embossed carrier tape(330 mmf reel to 254 mmf reel)
