Interrupts for the Upper CAPCOM Channels
The upper four CAPCOM channels (CC28IO … CC31IO) are not connected to the
respective interrupt nodes (CC28IC … CC31IC). However, these signals share the same
pins as the fast external interrupts EX0IN … EX3IN. Due to this fact the missing interrupt
nodes can be replaced.
Instead of the dedicated interrupt nodes for the CAPCOM registers 28 … 31 the fast
external interrupts 0 … 3 can be enabled if the corresponding pin is used as capture input
or compare output (compare modes 1 and 3). Register EXICON selects the interrupt
edge, registers CC8IC … CC11IC control interrupt enables and levels.
This means that CAPCOM channel 28 triggers external interrupt signal EX0IN and
requests an interrupt via node CC8IC. The other three channels are associated
accordingly (see
Table
5-9).
