• Queued analog-to-digital converter (QADC):
• – Eight analog input channels
• – 10-bit resolution ±2 counts accuracy
• – Minimum 7 µs conversion time
• – Internal sample and hold
• – Programmable input sample time for various source impedances
• – Two conversion command queues with a total of 64 entries
• – Subqueues possible using pause mechanism
• – Queue complete and pause software interrupts available on both queues
• – Queue pointers indicate current location for each queue
• – 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
• – Single-scan or continuous-scan of queues
• – Output data readable in three formats:
• Right-justified unsigned
• Left-justified signed
• Left-justified unsigned
• – Unused analog channels can be used as digital input/output (I/O)
• – Minimum pin set configuration implemented (Continue)
