Description

PWR USB Type-C power delivery register

Fields

UCPD_DBDIS

USB Type-C and power delivery 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 case, either to stop this pull-down or to hand over control to the UCPD (which should therefore be initialized before doing the disable).

0 (B_0x0): Enable USB Type-C dead battery pull-down behavior on UCPDx_CC1 and UCPDx_CC2 pins.

1 (B_0x1): Disable USB Type-C dead battery pull-down behavior on UCPDx_CC1 and UCPDx_CC2 pins.

UCPD_STBY

USB Type-c and Power delivery 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, and it must be written to 0 after exiting the standby mode and before writing any UCPD register.
