10.4 MULTIFUNCTION TIMER (MFT)
10.4.1 Introduction
The Multifunction Timer (MFT) peripheral offers
powerful timing capabilities and features 12 oper-
ating modes, including automatic PWM generation
and frequency measurement.
The MFT comprises a 16-bit Up/Down counter
driven by an 8-bit programmable prescaler. The in-
put clock may be INTCLK/3 or an external source.
The timer features two 16-bit Comparison Regis-
ters, and two 16-bit Capture/Load/Reload Regis-
ters. Two input pins and two alternate function out-
put pins are available.
Several functional configurations are possible, for
instance:
– 2 input captures on separate external lines, and

2 independent output compare functions with the
counter in free-running mode, or 1 output com-
pare at a fixed repetition rate.
– 1 input capture, 1 counter reload and 2 inde-
– 2 alternate autoreloads and 2 independent out-
– 2 alternate captures on the same external line
When two MFTs are present in an ST9 device, a
combined operating mode is available.
An internal On-Chip Event signal can be used on
some devices to control other on-chip peripherals.
The two external inputs may be individually pro-
grammed to detect any of the following:
– rising edges
– falling edges
– both rising and falling edges
