Overview
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
⢠âLegacyâ 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
â All channels configured to have alternate function as general purpose input/output pins
â 10-bit ±3 counts accuracy (TUE)
⢠External multiplexer support to increase as many as 23 channels
â Automatic 1 Ã 8 multiplexer control
â External multiplexer connected to a dedicated input channel
â 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
â Supports access to result and injection status with single 32-bit read
⢠Independently enabling of function for channels:
â Pre-sampling
â Offset error cancellation
â Offset refresh
⢠Conversion Triggering support
â Internal conversion triggering from periodic interrupt timer (PIT)
⢠Four configurable analog comparator channels offering range comparison with triggered alarm
â Greater than
â Less than
â Out of range
