2. The RTC CLKEN bit (bit number 16) of CTRL register is not available.
1. Stalled memory access instruction writeback fails if followed by a HW breakpoint.
1. Wrong PDCA behavior when using two PDCA channels with the same PID.
1. The TWI RXRDY flag in SR register is not reset when a software reset is performed.
Fix/Workaround
Do not use the CLKEN bit of the RTC on Rev E.
Consider the following assembly code sequence:
A
B
If a hardware breakpoint is placed on instruction B, and instruction A is a memory access
instruction, register file updates from instruction A can be discarded.
Fix/Workaround
Do not place hardware breakpoints, use software breakpoints instead.
Alternatively, place a hardware breakpoint on the instruction before the memory
access instruction and then single step over the memory access instruction.
Workaround/fix
The same PID should not be assigned to more than one channel.
Fix/Workaround
After a Software Reset, the register TWI RHR must be read.
