●Product Category:
■8-bit Microcontrollers
●Description of Change:
■Initial document release
■The content of the document has been restructured from:
▲ATtiny1614 Silicon Errata and Data Sheet Clarification
▲ATtiny1616/3216 Silicon Errata and Data Sheet Clarification
▲ATtiny1617/3217 Silicon Errata and Data Sheet Clarification to:
◆ATtiny1614/1616/1617 Silicon Errata and Data Sheet Clarification
◆ATtiny3216/3217 Silicon Errata and Data Sheet Clarification (this document)
■Refer to 4.2 Appendix - Obsolete Revision History for further details. The following items are referring to changes between the latest revisions of the obsolete documents and this document:
▲Added erratas:
◆Device: Writing the OSCLOCK Fuse in FUSE.OSCCFG to '1' Prevents Automatic Loading of Calibration Values
◆USART: Open-Drain Mode Does Not Work When TXD is Configured as Output
▲Removed erratas not applicable for ATtiny3216/3217
◆AC:• AC Interrupt Flag Not Set Unless Interrupt is Enabled.• False Triggers May Occur Under Certain Conditions.
• False Triggering When Sweeping Negative Input of the AC When the Low-Power Mode is Disabled
◆ADC:• SAMPDLY and ASDV Does Not Work Together With SAMPLEN.• ADC Interrupt Flags Cleared When Reading RESH.• Changing ADC Control Bits During Free-Running Mode not Working.• Changing ADC Control Bits During Free-Running Mode not Working.• ADC Wake-Up with WCOMP
◆TCB:• The TCB Interrupt Flag is Cleared When Reading CCMPH.• TCB Input Capture Frequency and Pulse-Width Measurement Mode Not Working with Prescaled Clock
◆TCD:• TCD Event Output Lines May Give False Events.• TCD Auto-Update Not Working
◆TWI:• TIMEOUT Bits in the TWI.MCTRLB Register are Not Accessible.• TWI Master Mode Wrongly Detects the Start Bit as a Stop Bit.• TWI Smart Mode Gives Extra Clock Pulse.• The TWI Master Enable Quick Command is Not Accessible
◆USART:• Full Range Duty Cycle Not Supported When Validating LIN Sync Field
▲Removed data sheet clarifications, as the corresponding data sheet has been updated with correct information
●Reason for Change:To Improve Productivity
