e2396: eSCI : Stop Mode not entered in LIN mode
Errata type: Errata
Description: When the eSCI module is in LIN mode and transmits the Header of an LIN RX frame, if the
CPU requests Stop Mode, the eSCI module may not acknowledge the Stop Mode request and
will stay in Normal Operating Mode (not in lower power stop mode).
Workaround: The application should ensure that no LIN transmission is running before it requests Stop
Mode by checking the Transmit Active and Receive Active status bits in the eSCI Interrupt Flag
and Status Register (eSCI_IFSR1[TACT] and eSCI_IFSR1[RACT]).
e1297: eSCI : reads of the SCI Data Register, which clears the RDRF flag, may cause
loss of frame if read occurs during reception of the STOP bit
Errata type: Errata
Description: A received SCI frame is not written into the SCI Data Registers and the Overrun (OR) flag is
not set in the SCI Status Register 1 (SCISR1), if:
1.) The eSCI has received the last data bit of an SCI frame n
2.) and the Receive Data Register Full (RDRF) flag is still set in the SCISR1 after the reception
of SCI frame n-1
3.) and during the reception of the STOP bit of frame n the host reads the SCI Data Registers,
and clears the RDRF flag
In this case the RDRF flag is erroneously set again by the controller instead of the OR flag.
Thus, the host reads the data of frame n-1 a second time, and the data of frame n is lost.
Workaround: The application should ensure that the data of the foregoing frame is read out from the SCI
Data Registers before the last data bit of the actual frame is received.
e1381: eSCI: LIN Wakeup flag set after aborted LIN frame transmission
Errata type: Errata
Description: If the eSCI module is transmitting a LIN frame and the application sets and clears the LIN
Finite State Machine Resync bit in the LIN Control Register 1 (eSCI_LCR1[LRES]) to abort the
transmission, the LIN Wakeup Receive Flag in the LIN Status Register may be set
(LWAKE=1).
Workaround: If the application has triggered LIN Protocol Engine Reset via the eSCI_LCR1[LRES], it should
wait for the duration of a frame and clear the eSCI_IFSR2[LWAKE] flag before waiting for a
wakeup.
e1221: eSCI: LIN bit error indicated at start of transmission after LIN reset
Errata type: Errata
