DMA
A programmable DMA channel may be assigned by CPU firmware to service each SSP
channel for fast and direct transfers between the SSP bus and SRAM with little CPU
involvement. Both DMA single-transfers and DMA burst-transfers are supported for transmit
and receive. Burst transfers require that FIFOs are enabled.
General purpose I/O
There are up to 80 GPIO pins available on 10 I/O ports for 128-pin and 144-ball devices, and
up to 40 GPIO pins on 5 I/O ports for 80-pin devices. Each and every GPIO pin by default
(during and just after a reset condition) is in high-impedance input mode, and some GPIO
pins are additionally routed to certain peripheral function inputs. CPU firmware may initialize
GPIO pins to have alternate input or output functions as listed in
logic state of any GPIO pin may be read by firmware as a GPIO input, regardless of its
reassigned input or output function.
Bit masking is available on each port, meaning firmware may selectively read or write
individual port pins, without disturbing other pins on the same port during a write.
Firmware may designate each GPIO pin to have open-drain or push-pull characteristics.
All GPIO pins are 5 V tolerant, meaning they can drive a voltage level up to VDDQ, and can
be safely driven by a voltage up to 5 V.
A/D converter (ADC) with DMA
The STR91xFA provides an eight-channel, 10-bit successive approximation analog-to-
digital converter. The ADC input pins are multiplexed with other functions on Port 4 as

0 to 3.6 V input range. External reference voltage input pin (AVREF) available on 128-
pin packages for better accuracy on low-voltage inputs. See
conditions, for restrictions to the relative voltage levels of VDDQ, AVDD, AVREF, and
AVREF_AVDD.
CPU Firmware may convert one ADC input channel at a time, or it has the option to set
the ADC to automatically scan and convert all eight ADC input channels sequentially
before signalling an end-of-conversion
Automatic continuous conversion mode is available for any number of designated ADC
input channels
Analog watchdog mode provides automatic monitoring of any ADC input, comparing it
against two programmable voltage threshold values. The ADC unit will set a flag or it
will interrupt the CPU if the input voltage rises above the higher threshold, or drops
below the lower threshold.
The ADC unit goes to stand-by mode (very low-current consumption) after any reset
event. CPU firmware may also command the ADC unit to stand-by mode at any time.
ADC conversion can be started or triggered by software command as well as triggers
from Timer/Counter (TIM), Motor Controller and input from external pin.
