EXTENDED FUNCTION TIMER (Cont’d)
10.3.4 Interrupt Management
The interrupts of the Extended Function Timer are
mapped on one of the eight External Interrupt
Channels of the microcontroller (refer to the “Inter-
rupts” chapter).
The three interrupt sources are mapped on the
same interrupt channel. To use them, the EFTIS
bit must be set)
Each External Interrupt Channel has:
– A trigger control bit in the EITR register (R242 -
– A pending bit in the EIPR register (R243 - Page
– A mask bit in the EIMR register (R244 - Page 0).
Program the interrupt priority level using the EI-
PLR register (R245 - Page 0). For a description of
these registers refer to the “Interrupts” and “DMA”
chapters.
Using the external interrupt channel for all EFT
interrupts
To use the interrupt features, perform the following
sequence:
– Set the priority level of the interrupt channel used
– Select the interrupt trigger edge as rising edge
– Set the EFTIS bit of the CR3 register to select

an interrupt event period is narrower than the
duration of the interrupt treatment. Otherwise
nested interrupt mode must be used to serve
higher priority requests.
