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 />
