ST92163 - 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).
