PINI/OTYPE(4)DESCRIPTION
NAMENO.
HWTEST_ENC10I6Manufacturing test enable signal. Connect this signal directly to ground on the PCB for normal operation.
PARKZC13I6DMD fast park control (active low Input with a hysteresis buffer). This signal is used to quickly park the DMD when loss of power is imminent. The longest lifetime of the DMD may not be achieved with the fast park operation; therefore, this signal is intended to only be asserted when a normal park operation is unable to be completed. The PARKZ signal is typically provided from the DLPAxxxx interrupt output signal.
JTAGTCKP12I6TI internal use. Leave this pin unconnected.
JTAGTDIP13I6TI internal use. Leave this pin unconnected.
JTAGTDO1N13(1)O1TI internal use. Leave this pin unconnected.
JTAGTDO2N12(1)O1TI internal use. Leave this pin unconnected.
JTAGTMS1M13I6TI internal use. Leave this pin unconnected.
JTAGTMS2N11I6TI internal use. Leave this pin unconnected.
JTAGTRSTZP11I6TI internal use.
This pin must be tied to ground, through an external resistor for normal operation. Failure to tie this pin low during normal operation can cause start up and initialization problems.(2)
RESETZC11I6Power-on reset (active low input with a hysteresis buffer). Self-configuration starts when a low-to-high transition is detected on RESETZ. All controller power and clocks must be stable before this reset is de-asserted. No signals are in their active state while RESETZ is asserted. This pin is typically connected to the RESETZ pin of the DLPA200x or RESET_Z of the DLPA300X.
TSTPT_0R12I/O1Test pins (includes weak internal pulldown). Pins are tri-stated while RESETZ is asserted low. Sampled as an input test mode selection control approximately 1.5 µs after de-assertion of RESETZ, and then driven as outputs.(2)(3)

Normal use: reserved for test output. Leave open for normal use.
Note: An external pullup may put the DLPC1438 in a test mode. See Section 7.3.6 for more information.
TSTPT_1R13I/O1
TSTPT_2R14I/O1
TSTPT_3R15I/O1
TSTPT_4P14I/O1Test pin 4 (Includes weak internal pulldown) – tri-stated while RESETZ is asserted low. Sampled as an input test mode selection control approximately 1.5 μs after de-assertion of RESETZ and then driven as an output.
TSTPT_5P15I/O1Test pins (includes weak internal pulldown). Pins are tri-stated while RESETZ is asserted low. Sampled as an input test mode selection control approximately 1.5 µs after de-assertion of RESETZ, and then driven as outputs.(2)(3)

Normal use: reserved for test output. Leave open for normal use.
Note: An external pullup may put the DLPC1438 in a test mode. See Section 7.3.6 for more information.
