Description

PWR USB Type-C™ and Power Delivery register

Fields

UCPD_DBDIS

UCPD dead battery disable After exiting reset, the USB Type-C “dead battery” behavior is enabled, which may have a pull-down effect on CC1 and CC2 pins. It is recommended to disable it in all cases, either to stop this pull-down or to handover control to the UCPD (the UCPD must be initialized before doing the disable).

0 (B_0x0): UCPD dead battery pull-down behavior enabled on UCPDx_CC1 and UCPDx_CC2 pins

1 (B_0x1): UCPD dead battery pull-down behavior disabled on UCPDx_CC1 and UCPDx_CC2 pins

UCPD_STBY

UCPD Standby mode When set, this bit is used to memorize the UCPD configuration in Standby mode. This bit must be written to 1 just before entering Standby mode when using UCPD. It must be written to 0 after exiting the Standby mode and before writing any UCPD registers.
