Features

Freescale Semiconductor

14

•

Supports byte (8-bit), half word (16-bit), and word (32-bit) writes for optimal use of memory

2.4.11

QuadSPI serial flash controller

The QuadSPI module enables use of external serial flash memories supporting single, dual and quad

modes of operation. It features the following:

•

Memory mapping of external serial flash

•

Automatic serial flash read command generation by CPU, DMA or DCU read access on AHB bus

•

Supports single, dual and quad serial flash read commands

•

Flexible buffering scheme to maximize read bandwidth of serial flash

•

‘Legacy’ mode allowing QuadSPI to be used as a standard SPI (no DSI or CSI mode)

2.4.12

Analog-to-digital converter (ADC)

The ADC features the following:

•

10-bit A/D resolution

•

0 to 5 V common mode conversion range

•

Supports conversions speeds of up to 1

s

•

16 internal and 8 external channels support

•

Up to 16 single-ended inputs channels

— All channels configured to have alternate function as general purpose input/output pins

– 10-bit ±3 counts accuracy (TUE)

•

External multiplexer support to increase up to 23 channels

— Automatic 1 × 8 multiplexer control

— External multiplexer connected to a dedicated input channel

— Shared register between the 8 external channels

•

Result register available for every non-multiplexed channel

•

Configurable left- or right-aligned result format

•

Supports for one-shot, scan and injection conversion modes

•

Injection mode status bit implemented on adjacent 16-bit register for each result

— Supports access to result and injection status with single 32-bit read
