Input Capture Edge Register (ICE)

The input capture edge register has a function to indicate the selected edge direction
and to select whether the input signal is inputted from either external pin or LIN-UART.
By cooperating with the LIN-UART, the baud rate measurement at the LIN slave
operation can be performed.
The correspondence between ICE01 to ICE23 / channel name and input pin (UART)
name is shown as follows.
ICE01: input capture ch0, ch1 IN0(/UART0) IN1(/UART1)
ICE23: input capture ch2, ch3 IN2
