Revision 10
1-11
Table 1-5 describes the different configuration requirements of BST pins and their functionality in different
modes.
TRST Pin
The TRST pin functions as a dedicated Boundary-Scan Reset pin when the Reserve JTAG Test Reset
option is selected, as shown in Figure 1-12. An internal pull-up resistor is permanently enabled on the
TRST pin in this mode. It is recommended to connect this pin to GND in normal operation to keep the
JTAG state controller in the Test-Logic-Reset state. When JTAG is being used, it can be left floating or be
driven HIGH.
When the Reserve JTAG Test Reset option is not selected, this pin will function as a regular I/O. If
unused as an I/O in the design, it will be configured as a tristated output.
JTAG Instructions
Table 1-6 lists the supported instructions with the corresponding IR codes for eX devices.
Table 1-7 lists the codes returned after executing the IDCODE instruction for eX devices. Note that bit 0
is always “1.” Bits 11-1 are always “02F”, which is Microsemi SoC Products Group's manufacturer code.
