4. Reset of Timer-2 flags in asynchronous mode
3. Miss-functioning when code stack is in XRAM
2. Extra consumption in power reduction modes
1. Power supply current in Power-down mode
In asynchronous mode, a writing in any register of the TIMER-2 (TCCR2A, TCNT2 &
OCR2A) automatically clears TOV2 and OCF2A flags in TFIR register.
Problem fix / workaround
– TOV2: Do not write in Timer-2 registers if TCNT2 is equal to 0xFF, 0x00 or 0x01.
– OCF2A: Do not write in Timer-2 registers if TCNT2 and OCR2A differ from -1, 0 or 1.
If the stack pointer (SP) targets the XRAM and if the execution of an instruction is split to
serve a rising interrupt, the last operation of this instruction, executed after pushing out the
return address from XRAM, may be disturbed providing wrong data to the system.
Example: - the “OUT” instruction can be executed twice
Problem fix / workaround
Map the code stack in internal SRAM.
When AVCC is selected as voltage reference for ADC (REF[1,0]=0,1), an extra consumption
close to 30 µA (5.0V/25°C) appears in power reduction modes.
Problem fix / workaround
Switch from AVCC to AREF pin (REF[1,0]=0,0) before enabling one of the power reduction
modes.
