23.3.1 System Configuration Control Register (SYSCFG)
SYSCFG is a register that enables high-speed operation, selects the host controller function or
function controller function, controls the DP and DM pins, controls the full-speed receiver and
controls a software reset for this module.
This register is initialized by a power-on reset.

R/W Description
R
Reserved
These bits are always read as 0. The write value
should always be 0.
R/W High-Speed Operation Enable
0: High-speed operation is disabled
1: High-speed operation is enabled (detected by this
module)
R/W Controller Function Select
Selects the host controller function or function
controller function.
0: Function controller function is selected.
1: Host controller function is selected.
R/W D− Line Resistor Control
R/W D+ Line Resistor Control
Sets D− and D+ line resistors. Before setting these
bits, the HSE and DCFM bits should be set.
00: D− and D+ are open.
01: D− is open and D+ is pulled up.
10: D− and D+ are pulled down.
11: D− is pulled down and D+ is pulled up.
