to the Incorrect Address
EHPI_7 HRDY is Always Driven
RTC_3 RTC Interrupts are Perceived by the User as Happening One Second Before
RTC_4 Any Year Ending in 00 Will Appear as a Leap Year
RTC_5 Midnight and Noon Transitions Do Not Function Correctly in 12h Mode
USB_2 CPU Might Miss Back-to-Back USB Interrupts When CPU Speed is Less Than or Equal to 24 MHz
USB_5 USB Input Cell Does Not Power Down When USB is Placed in IDLE
CPU Read/Write to USB Module may Return Incorrect Result if the USB Clock is Running Slower Than
USB_6
Recommended Speed (48 MHz)
