7. Q&A
7.1 What are the varieties of active edge polarity for external input, and how do I select
them?
The active edge polarity varieties consist of rising, falling, and both, for a total of 3, and are set using the
external input active edge selection bit (ICS01.EG[01:00]) and (ICS01:EG[11:10]), (ICS23.EG[01:00]) and
(ICS23:EG[11:10]), (ICS45.EG[01:00]) and (ICS45:EG[11:10]), (ICS67.EG[01:00]) and (ICS67:EG[11:10]).
To select rising edge
To select falling edge
To select both edges
7.2 What about setting the external input pins (ICU0-7)?
Use the port function register and extra port function bits (PFR14.x/EPFR14.x).
Operation
To set it to the external input pins (ICU0)
To set it to the external input pins (ICU1)
To set it to the external input pins (ICU2)
To set it to the external input pins (ICU3)
To set it to the external input pins (ICU4)
To set it to the external input pins (ICU5)
To set it to the external input pins (ICU6)
To set it to the external input pins (ICU7)
Remark: When setting the Extra port function register EPFR14.x to "1" the corresponding input capture macro
is internally connected to the corresponding LIN-USART macro for LIN Sync Field measurement. Hence, with
this setting the corresponding ICU channel is not available as external input.
7.3 What about interrupt-related registers?
Input capture interrupt vector and input capture interrupt level settings
The relationship between input capture number, interrupt level, and vector is explained in the following table.
