Spy-Bi-Wire Interface

In addition to the standard JTAG interface, the MSP430 family supports the two wire Spy-Bi-Wire

interface. Spy-Bi-Wire can be used to interface with MSP430 development tools and device programmers.

Table 6-7 lists the Spy-Bi-Wire interface 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 SBW 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 6-7. Additional information can

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