TRST: Test Reset (Active Low)
A low signal on this pin will reset the JTAG test port anytime. This pin is a Schmitt-triggered input with an internal
pull-up resistor. It must be connected to the RST pin or ground when JTAG is not used.
TMS: Test Mode Select
The signal on this pin controls the JTAG test performance and is clocked into the device on the rising edge of the
TCK. This pin has an internal pull-up resistor.
TCK: Test Clock
The clock for the JTAG test is input on this pin. The TDI and the TMS are clocked into the device on the rising edge
of the TCK and the TDO is clocked out of the device on the falling edge of the TCK.
TDI: Test Input
The test data are input on this pin. It is sampled on the rising edge of the TCK. This pin has an internal pull-up resis-
tor.
TDO: Test Output
The test data are output on this pin. It is sampled on the falling edge of the TCK. This pin is in tri-state mode, except
during the process of scanning of the data.
BIAS: +5V Bias
This pin enables +5 V tolerance on the inputs. When +5 V tolerance inputs are required, the BIAS must be con-
nected to a well-decoupled +5 V rail. When +3 V input is required, the BIAS must be connected to a well-decoupled
+3.3 V DC supply.
During power up, the BIAS pin should be powered no later than any VDDC/VDDIO pin is powered.
VDDIO[3:0]:
These pins must be connected to a common, well-decoupled +3.3 V DC supply together with the core power pins
VDDC[4:0] externally.
VDDC[4:0]:
These pins must be connected to a common, well-decoupled +3.3 V DC supply together with the pad ring power
pins VDDIO[3:0] externally.
The VDDC[5:12] are extra power pins for PBGA.
GNDIO[3:0]:
These pins must be connected to a common ground together with the core ground pins GNDC[4:0].
