ST STM32G471 User Manual

USB Type-C™ / USB Power Delivery interface (UCPD) RM0440
2066/2126 RM0440 Rev 4
Bits 31:22 Reserved, must be kept at reset value.
Bit 21 CC2TCDIS:CC2 Type-C detector disable
The bit disables the Type-C detector on the CC2 line.
0: Enable
1: Disable
When enabled, the Type-C detector for CC2 is configured through ANAMODE and
ANASUBMODE[1:0].
Bit 20 CC1TCDIS: CC1 Type-C detector disable
The bit disables the Type-C detector on the CC1 line.
0: Enable
1: Disable
When enabled, the Type-C detector for CC1 is configured through ANAMODE and
ANASUBMODE[1:0].
Bit 19 Reserved, must be kept at reset value.
Bit 18 RDCH: Rdch condition drive
The bit drives Rdch condition on the CC line selected through the PHYCCSEL bit (thus
associated with VCONN), by remaining set during the source-only UnattachedWait.SRC
state, to respect the Type-C state. Refer to "USB Type-C ECN for Source VCONN
Discharge". The CCENABLE[1:0] bitfield must be set accordingly, too.
0: No effect
1: Rdch condition drive
Bit 17 FRSTX: FRS Tx signaling enable.
Setting the bit enables FRS Tx signaling.
0: No effect
1: Enable
The bit is cleared by hardware after a delay respecting the USB Power Delivery specification
Revision 3.0.
Bit 16 FRSRXEN: FRS event detection enable
Setting the bit enables FRS Rx event (FRSEVT) detection on the CC line selected through
the PHYCCSEL bit. 0: Disable
1: Enable
Clear the bit when the device is attached to an FRS-incapable source/sink.
Bit 15 Reserved, must be kept at reset value.
Bit 14 Reserved, must be kept at reset value.
Bit 13 Reserved, must be kept at reset value.
Bit 12 Reserved, must be kept at reset value.
Bits 11:10 CCENABLE[1:0]: CC line enable
This bitfield enables CC1 and CC2 line analog PHYs (pull-ups and pull-downs) according to
ANAMODE and ANASUBMODE[1:0] setting.
0x0: Disable both PHYs
0x1: Enable CC1 PHY
0x2: Enable CC2 PHY
0x3: Enable CC1 and CC2 PHY
A single line PHY can be enabled when, for example, the other line is driven by VCONN via
an external VCONN switch. Enabling both PHYs is the normal usage for sink/source.
