Functional overview
STR91xFAxxx
Each SSP interface on the STR91xFA has the following features:
●
Full-duplex, three or four-wire synchronous transfers
●
Master or Slave operation
●
Programmable clock bit rate with prescaler, up to 24 MHz for Master mode and 4 MHz
for Slave mode
●
Separate transmit and receive FIFOs, each 16-bits wide and 8 locations deep
●
Programmable data frame size from 4 to 16 bits
●
Programmable clock and phase polarity
●
Specifically for MICROWIRE protocol:
–
Half-duplex transfers using 8-bit control message
●
Specifically for SSI protocol:
–
Full-duplex four-wire synchronous transfer
–
Transmit data pin tri-stateable when not transmitting
3.22.1
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.
3.23
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 Table 8. At any time, the
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 5V tolerant, meaning they can drive a voltage level up to VDDQ, and can
be safely driven by a voltage up to 5V.
