Philips Semiconductors PNX2000

Audio video input processor

[1] It is recommended to bias this pad with a 10 kΩ resistor

[1] It is recommended to pull-down TRST_N with a 10 kΩ resistor. This ensures correct reset state of internal

TAP circuitry and cor rect POR of the device within defined state machine.
