List........16 7. I/O Multiplexing and Considerations 18 7.1. Multi.

Features

In-system programmable Flash, 12-channel Direct Memory Access Controller (DMAC), 12-channel Event System, programmable Interrupt Controller, 52 programmable I/O pins, 32-bit Real-Time Clock and Calendar (RTC), five 16-bit Timer/Counters (TC) and four 24-bit Timer/Counters for Control (TCC), where each TC can be configured to perform frequency and waveform generation, accurate program execution timing or input capture with time and frequency measurement of digital signals. The TCs can operate in 8-bit or 16-bit mode, selected TCs can be cascaded to form a 32-bit TC, and three timer/counters ha.
