First Analog Comparator conversion may be delayed

If the device is powered by a slow rising VCC, the first Analog Comparator conversion will take longer than expected on some devices.

Problem Fix/Workaround

When the device has been powered or reset, disable then enable theAnalog Comparator before the first conversion. Interrupts may be lost when writing the timer registers in the asynchronous time to Break IC PIC16C74 Code. The interrupt will be lost if a timer register that is synchronized to the asynchronous timer clock is written when the asynchronous Timer/Counter register(TCNTx) is 0x00 if Recover Microcontroller ATmega16A Software.

Problem Fix / Workaround

Always check that the asynchronous Timer/Counter register neither have the value 0xFF nor 0x00 before writing to the asynchronous Timer Control Register(TCCRx), asynchronous Timer Counter Register(TCNTx), or asynchronous Output Compare Register(OCRx) for the purpose of Copy Chip PIC16C73A Program.

IDCODE masks data from TDI input

The JTAG instruction IDCODE is not working correctly. Data to succeeding devices are replaced by all-ones during Update-DR.

Problem Fix / Workaround

If ATmega16 is the only device in the scan chain, the problem is not visible.

Select the Device ID Register of the ATmega16 by issuing the IDCODE instruction or by entering the Test-Logic-Reset state of the TAP controller to recover out the contents of its Device ID Register and possibly data from succeeding devices of the scan chain. Issue the BYPASS instruction to the ATmega16 while recovering the Device ID Registers of preceding devices of the boundary scan chain before Recover Microcontroller ATmega16A Software.

If the Device IDs of all devices in the boundary scan chain must be captured simultaneously, the ATmega16 must be the fist device in the chain of Reverse Engineering Microcontroller PIC16F73 Program.

Recovering EEPROM by using ST or STS to set EERE bit triggers unexpected interrupt request.

Recovering EEPROM by using the ST or STS command to set the EERE bit in the EECR register triggers an unexpected EEPROM interrupt request.

Problem Fix / Workaround

Always use OUT or SBI to set EERE in EECR.

First Analog Comparator conversion may be delayed to Unlock Microcontroller

Interrupts may be lost when writing the timer registers in the asynchronous timer IDCODE masks data from TDI input

Recovering EEPROM by using ST or STS to set EERE bit triggers unexpected interrupt request. First Analog Comparator conversion may be delayed before Recover Microcontroller ATmega16A Software

If the device is powered by a slow rising VCC, the first Analog Comparator conversion will take longer than expected on some devices after Recover MCU PIC16C72 Software.

Problem Fix/Workaround

When the device has been powered or reset, disable then enable theAnalog Comparator before the first conversion.
