DESCRIPTION
NAME
NO.
TEST/DEBUG (T/D) (CONTINUED)
Test enable. Reserved for internal use only. TI recommends that this pin be
IPD (20 μA)
connected to ground or pulled down to ground by an external resistor.
Serial input for controlling the state of the CPU test access port (TAP)
IPU (20 μA)
controller (JTAG)
Serial input for controlling the second TAP. TI recommends that this pin be
IPU (20 μA)
connected to V
CCIO
or pulled up to V
CCIO
by an external resistor.
Test hardware reset to TAP1 and TAP2. IEEE Standard 1149-1 (JTAG)
IPD (20 μA)
Boundary-Scan Logic. TI recommends that this pin be pulled down to ground
by an external resistor.
FLASH
Flash test pad 1.
For proper operation, this pin must not be connected
[no connect (NC)].
Flash test pad 2.
For proper operation, this pin must not be connected
[no connect (NC)].
Flash external pump voltage (3.3 V). This pin is required for both flash read
and flash program and erase operations.
