ISWCLKClock input
I/OSWDIOBidirectional serial data

The devices in the PIC32CM PL10 family support Arm’s CoreSight Serial Wire Interface. This interface consists of two pins: SWCLK, a clock signal that is always an input to the device, and SWDIO, a bidirectional data pin. This interface provides access to all of Arm’s customer-visible debug features.

This section summarizes the critical details of this interface for production test and validation.

Refer to the Arm® Debug Interface Architecture Specification ADIv5.0 to ADIv5.2 (IHI 0031) for more details.
