CHAPTER 13 16-Bit I/O TIMER
Note:
In the input capture 0 and 1, if the input signal is selected to the LIN-UART (ICE01:ICUS), the input
capture is used to calculate the baud rate when the LIN-UART operates the LIN slave. In this case, it
must be set to the input capture interrupt enable (ICS01:ICE0=1 or ICE1=1) and to the detection of both
edges (ICS01:EG01, EG00=11
B
or EG11, EG10=11
B
). See "20.7.3 Operation with LIN Function
(Operation Mode 3)" for details of the baud rate calculation.

Undefined bits Read : The value is undefined.
Write: No effect.
bit9 IEI3:
Detection edge indication bit 3 This bit indicates the edges detected by the input capture 3 (rising/falling).
This bit is read only.
"0": Indicate that falling edge is detected.
"1": Indicate that rising edge is detected.
Note: This bit value is disabled when the capture operation is stopped
(ICSnm : EGm1, EGm0="00"). (n=2, m=n+1)
bit8 IEI2 :
Detection edge indication bit 2 This bit indicates the edges detected by the input capture 2 (rising/falling).
This bit is read only.
"0": Indicate that falling edge is detected.
"1": Indicate that rising edge is detected.
Note: This bit value is disabled when the capture operation is stopped
(ICS23 : EG21, EG20="00").
