Functional Problems<br />
• If hardware traps (including NMI) can occur, add the corresponding interrupt vectors<br />
to PRAM and modify register VECSEG to point to the PRAM space.<br />
• In order to support return to idle/sleep mode after a PEC transfer, e.g. a semaphore<br />
bit may be used. This bit may be set to '1' before the IDLE instruction is executed. All<br />
trap and interrupt service routines invoked after wake up from idle/sleep should clear<br />
this bit to '0'. After having returned to the program in the internal flash and having<br />
enabled the interrupt system, this bit should be tested (allow a sufficient time of e.g.<br />
12 cycles for interrupt arbitration), and if it is still at '1' (i.e. no interrupts/traps have<br />
occurred), repeat the auxiliary routine that prepares for re-entry into idle/sleep mode.<br />
ASC_X.001 ASC Autobaud Detection in 8-bit Modes with Parity<br />
The Autobaud Detection feature of the Asynchronous/Synchronous Serial Interface<br />
(ASC) does not work correctly for 8-bit modes with even or odd parity.<br />
The Autobaud Detection feature works correctly for 7-bit modes with even or odd parity,<br />
and for 8-bit modes without parity.<br />
GPT12E_X.001 T5/T6 in Counter Mode with BPS2 = 1X B<br />
When T5 and/or T6 are configured for counter mode (bit field TxM = 001 B in register<br />
GPT12E_TxCON, x = 5, 6), and bit field BPS2 = 1X B in register GPT12E_T6CON, then<br />
edge detection for the following count input and control signals does not work correctly:<br />
T5IN, T6IN, T5EUD, T6EUD.<br />
Note: The configuration where T5 counts the overflow/underflow events of T6 is not<br />
affected by this problem.<br />
Workaround<br />
Do not set bit field BPS2 = 1X B in register GPT12E_T6CON when T5 and/or T6 are<br />
configured for counter mode. Use only settings BPS2 = 0X B when T5 and/or T6 are<br />
configured for counter mode.<br />
