NOTE

To invoke the BSL from the DVIO domain, the RST/NMI pin and the BSLEN pin must be

used for the entry sequence (see Section 5.49). It is critical not to confuse the RST/NMI pin

with the RSTDVCC/SBWTDIO pin. In many other MSP430 devices, SBWTDIO is shared with

the RST/NMI pin, and RSTDVCC does not exist. Additional information can be found in

Designing With MSP430F522x and MSP430F521x Devices (SLAA558).

JTAG Operation

6.6.1

JTAG Standard Interface

The MSP430 family supports the standard JTAG interface which requires four signals for sending and

receiving data. The JTAG signals are shared with general-purpose I/O. The TEST/SBWTCK pin is used to

enable the JTAG signals. In addition to these signals, the RSTDVCC/SBWTDIO is required to interface

with MSP430 development tools and device programmers. Table 6-6 lists the JTAG pin requirements. For

further details on interfacing to development tools and device programmers, see the MSP430™ Hardware

Tools User's Guide (SLAU278). For a complete description of the features of the JTAG interface and its

implementation, see MSP430™ Programming Via the JTAG Interface (SLAU320). Additional information

can be found in Designing With MSP430F522x and MSP430F521x Devices (SLAA558).

NOTE

All JTAG I/O pins are supplied by DVCC.

NOTE

Traditionally, on other MSP430 devices, the RST/NMI pin is used for SBWTDIO, so care

must be taken not to mistakenly use the incorrect pin. On the F525x series of devices, it is

required to use RSTDVCC for SBWTDIO as shown in Table 6-6. Additional information can

be found in Designing With MSP430F522x and MSP430F521x Devices (SLAA558).
