General Description
â Queue pointers indicate current location for each queue
â Automated queue modes initiated by:
External edge trigger and gated trigger
Periodic/interval timer, within queued analog-to-digital
converter (QADC) module {queue1 and queue2}
Software command
â Single-scan or continuous-scan of queues
â Output data readable in three formats:
Right-justified unsigned
Left-justified signed
Left-justified unsigned
â Unused analog channels can be used as digital input/output
(I/O)
â Minimum pin set configuration implemented
⢠Interrupt controller:
â Up to 40 interrupt sources
â 32 unique programmable priority levels for each interrupt
source
â Independent enable/disable of pending interrupts based on
priority level
â Select normal or fast interrupt request for each priority level
â Fast interrupt requests always have priority over normal
interrupts.
â Ability to mask interrupts at and below a defined priority level
â Ability to select between autovectored or vectored interrupt
requests
â Vectored interrupts generated based on priority level
â Ability to generate a separate vector number for normal and
fast interrupts
â Ability for software to self-schedule interrupts
â Software visibility of pending interrupts and interrupt signals to
core
â Asynchronous operation to support wakeup from low-power
modes
