16 / 130 page  Overview PXD10 Microcontroller Data Sheet, Rev. 1 Freescale Semiconductor 16 1.6.11 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) 1.6.12 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 as fast as 1 µs • 16 internal and 8 external channels support • As many as 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 as many as 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 • Independently enabling of function for channels: — Pre-sampling — Offset error cancellation —Offset refresh • Conversion Triggering support — Internal conversion triggering from periodic interrupt timer (PIT) • Four configurable analog comparator channels offering range comparison with triggered alarm — Greater than —Less than — Out of range |
