10.4.9 SPI0 and MCI Interface
SPI0 signals and MCI0 signals are multiplexed, as the DataFlash Card is hardware-compatible with the SDCard. Only
one can be used at a time.
10.4.10 Interrupts
Using IRQ0 prevents using the CAN controller.
Using FIQ prevents using DMA Request 2.
10.4.11 Image Sensor Interface
Using ISI in 8-bit data mode prevents using timers TIOA1, TIOB1.
10.4.12 Timers
Using TIOA2 and TIOB2, in this order, prevents using SPI1’s Chip Selects [2-3].
10.5 Embedded Peripherals Overview
10.5.1 Serial Peripheral Interface
z Supports communication with serial external devices
z Four chip selects with external decoder support allow communication with up to 15 peripherals
z Serial memories, such as DataFlash and 3-wire EEPROMs
z Serial peripherals, such as ADCs, DACs, LCD Controllers, CAN Controllers and Sensors
z External co-processors
z Master or slave serial peripheral bus interface
z 8- to 16-bit programmable data length per chip select
z Programmable phase and polarity per chip select
z Programmable transfer delays between consecutive transfers and between clock and data per chip select
z Programmable delay between consecutive transfers
z Selectable mode fault detection
z Very fast transfers supported
z Transfers with baud rates up to MCK
z The chip select line may be left active to speed up transfers on the same device
10.5.2 Two-wire Interface
z Master Mode only
z Compatibility with standard two-wire serial memory
z One, two or three bytes for slave address
z Sequential read/write operations
10.5.3 USART
z Programmable Baud Rate Generator
z 5- to 9-bit full-duplex synchronous or asynchronous serial communications
z 1, 1.5 or 2 stop bits in Asynchronous Mode or 1 or 2 stop bits in Synchronous Mode
z Parity generation and error detection
z Framing error detection, overrun error detection
z MSB- or LSB-first
z Optional break generation and detection
