PDI Physical
(PDI_CLK), and the dedicated Test pin for data input and output (PDI_DATA). A JTAG interface
is also available on most devices, and this can be used for programming and debugging through
the 4-pin JTAG interface. The JTAG interface is IEEE std. 1149.1 compliant, and supports
boundary scan. Unless otherwise stated, all references to the PDI assumes access through the
PDI physical. Any external programmer or on-chip debugger/emulator can be directly connected
to these interfaces, and no external components are required.
Figure 29-1. The PDI with JTAG and PDI physical and closely related modules (grey)
The PDI physical layer handles the basic low-level serial communication. The physical layer
uses a bi-directional half-duplex synchronous serial receiver and transmitter (as a USART in
USRT mode). The physical layer includes start-of-frame detection, frame error detection, parity
generation, parity error detection, and collision detection.
The PDI is accessed through two pins:
In addition to these two pins, V
