2.3.1 P1, JTAG Interface
2-8
The eZdsp
standard interface used by JTAG emulators to interface to Texas Instruments DSPs.
The positions of the 14 pins on the P1 connector are shown in the diagram below as
viewed from the top of the eZdsp.
The definition of P1, which has the JTAG signals is shown below.
The TMS320F28335 supports +3.3V Input/Output levels
which are NOT +5V tolerant. Connecting the eZdsp to
a system with +5V Input/Output levels will damage the
TMS320F28335. If the eZdsp is connected to another
target then the eZdsp must be powered up first and
powered down last to prevent lactchup conditions.
