MULTIFUNCTION TIMER (MFT)
MULTIFUNCTION TIMER (Cont’d)
The configuration of each input is programmed in
the Input Control Register.
Each of the two output pins can be driven from any
of three possible sources:
– Compare Register 0 logic
– Compare Register 1 logic
– Overflow/Underflow logic
Each of these three sources can cause one of the
following four actions, independently, on each of
the two outputs:
– Nop, Set, Reset, Toggle
In addition, an additional On-Chip Event signal can
be generated by two of the three sources men-
tioned above, i.e. Over/Underflow event and Com-
pare 0 event. This signal can be used internally to

synchronise another on-chip peripheral. Five
maskable interrupt sources referring to an End Of
Count condition, 2 input captures and 2 output
compares, can generate 3 different interrupt re-
quests (with hardware fixed priority), pointing to 3
interrupt routine vectors.
Two independent DMA channels are available for
rapid data transfer operations. Each DMA request
(associated with a capture on the REG0R register,
or with a compare on the CMP0R register) has pri-
ority over an interrupt request generated by the
same source.
A SWAP mode is also available to allow high
speed continuous transfers (see Interrupt and
DMA chapter).
