DMA
A programmable DMA channel may be assigned by CPU firmware to service each ADC
conversion result for fast DMA single-transfer.
Standard timers (TIM) with DMA
The STR91xFA has four independent, free-running 16-bit timer/counter modules designated
TIM0, TIM1, TIM2, and TIM3. Each general purpose timer/counter can be configured by
firmware for a variety of tasks including; pulse width and frequency measurement (input
capture), generation of waveforms (output compare and PWM), event counting, delay
timing, and up/down counting.
Each of the four timer units have the following features:

DMA
A programmable DMA channel may be assigned by CPU firmware to service each
timer/counter module TIM0 and TIM1 for fast and direct single transfers.
16-bit free running timer/counter
Internal timer/counter clock source from a programmable 8-bit prescale of the CCU
PCLK clock output
Optional external timer/counter clock source from pin P2.4 shared by TIM0/TIM1, and
pin P2.5 shared by TIM2/TIM3. Frequency of these external clocks must be at least 4
times less the frequency of the internal CCU PCLK clock output.
Two dedicated 16-bit Input Capture registers for measuring up to two input signals.
Input Capture has programmable selection of input signal edge detection
Two dedicated 16-bit Output Compare registers for generation up to two output signals
PWM output generation with 16-bit resolution of both pulse width and frequency
One pulse generation in response to an external event
A dedicated interrupt to the CPU with five interrupt flags
The OCF1 flag (Output Compare 1) from the timer can be configured to trigger an ADC
conversion
