Treatment of R/D Converter and A/D Converter Power Supply Pins

If unuse R/D converter and A/D converter, needs connection as follows.

− AVCC0 = AVCC1= AVCC2 = AVRH0= AVRH1 = AVRH2 = RVCC0 = RVCC1 = RVRH0 =RVRH1 =

VCC5

− AVSS0 = AVSS1 = AVSS2 = AVRL0 = AVRL1 = AVRL2 = AVR0 = AVR1 = RVSS0 = RVSS1 =

RVRL0 = RVRL1 = RVR0 = RVR1 = VSS

Note on Using External Clock

The external clock is unsupported.

External direct clock input cannot use.

Power-on Sequence of R/D Converter and A/D Converter Power Supply Analog Inputs

Be sure to turn on the digital power supply (VCC5, VCC12) first, and then turn on the R/D converter and A/D

converter power supplies*1 and analog inputs*2. Also, turn off the R/D converter and A/D converter power

supplies*1 and analog inputs*2 first, and then turn off the digital power supply (VCC5, VCC12).

When the AVRH0, AVRH1, AVRH2, RVRH0 and RVRH1 pin voltages are turned on or off, they must not

exceed AVCC0, AVCC1, AVCC2, RVCC0 and RVCC1. Even if a common analog input pin is used as an

input port, its input voltage must not exceed AVCC0, AVCC1 or AVCC2. (However, the analog power supply

voltage and digital power supply voltage can be turned on or off simultaneously.)

Notes When Writing Data in a Register Having the Status Flag

When writing data in the register that has a status flag (especially, an interrupt request flag) to control

function, take care not to clear its status flag erroneously. The program must be written not to clear the flag

to the status bit, and to set the control bits to have the desired value.

Especially, if multiple control bits are used, the bit instruction cannot be used. (The bit instruction can

access to a single bit only.) The Byte, Half-word, or Word access must be used to write data in the control

bits and status flag simultaneously. During this time, take care not to clear other bits (in this case, the bits of

status flag) erroneously.

Note:

−

These points can be ignored because the bit instructions already take the points into consideration

for registers that are supported by bit-band unit. These points must be considered when using the bit

instruction for registers that are not supported by bit-band unit.
