ZHCSFQ2C November 2016 – June 2018 TUSB422
PRODUCTION DATA.
The TUSB422 supports Fast Role Swap TX as defined in the USB Power Delivery 3.0 specification. The TUSB422 does not support Fast Role Swap RX function.
The TUSB422 can also transmit a FastRole swap pulse. This is done by writing a 1’b1 to the TX_FAST_ROLE_SWAP bit in the PHY BMC TX Control register. Upon setting this bit, the TUSB422 generates a FastRole swap pulse as defined by TFRSWAPTX parameter. The TUSB422 clears the TX_FAST_ROLE_SWAP bit after it has completed the transmission.
