On-chip flash memory
— Up to 1.5 MB flash memory, accessed via a 64-bit wide bus interface
— 16 KB shadow block
— Fetch Accelerator
— Censorship protection scheme to prevent flash content visibility
— Flash divided into two independent arrays, allowing reading from one array while erasing/programming the other
— Memory block:
— Hardware programming state machine
– User-selectable ability to generate a system reset upon loss of clock
– Backup clock (reference clock or FMPLL free-running) can be applied to the system in case of loss of clock
– Pin function selection
– Configurable weak pull-up or pull-down
– Drive strength
– Slew rate
– Hysteresis
– Allows flexible selection of eQADC trigger inputs (eTPU, eMIOS and external signals)
– Allows selection of interrupt requests between external pins and DSPI
– Provide single cycle flash access @ 80 MHz
– Quadruple 128-bit wide prefetch/burst buffers
– Prefetch buffers can be configured to prefetch code or data or both
array (used for EEPROM emulation)
