26.
Each MCU has an on-chip JTAG interface and logic to support boundary scan for production and in-sys-
tem testing, Flash read/write operations, and non-intrusive in-circuit debug. The JTAG interface is fully
compliant with the IEEE 1149.1 specification. Refer to this specification for detailed descriptions of the Test
Interface and Boundary-Scan Architecture. Access of the JTAG Instruction Register (IR) and Data Regis-
ters (DR) are as described in the Test Access Port and Operation of the IEEE 1149.1 specification.
The JTAG interface is accessed via four dedicated pins on the MCU: TCK, TMS, TDI, and TDO.
Through the 16-bit JTAG Instruction Register (IR), any of the eight instructions shown in Figure 26.1 can
be commanded. There are three DR’s associated with JTAG Boundary-Scan, and four associated with
Flash read/write operations on the MCU.
