Description
USB Data Line Status
Table 23.3 shows the USB data bus line status. The
line status (D+ and D− lines) of the USB data bus is
monitored using the setting of these bits.
The line status can be confirmed with the full-speed
receiver. This module automatically controls the full-
speed receiver by supplying USBCLK. However, the
full-speed receiver can be enabled using software,
without supplying USBCLK, by setting the FSRPC bit
in SYSCFG. After a power-on reset, D+ and D− line
status can be confirmed prior to the USBCLK supply
by setting the FSRPC bit to 1.
Once USBCLK is supplied, software setting is not
required.
