Section 23 USB 2.0 Host/Function Module (USB)

This section describes the register operations that are necessary to the initial settings of this

module, and the registers necessary for power consumption control.

Table 23.10 lists the types of controller resets. For the initialized states of the registers following

the reset operations, see section 23.3, Register Description.

Table 23.10 Types of Reset

This module can select the host controller function or function controller function using the

DCFM bit in SYSCFG.

This module can select a USB communication speed (communication bit rate) of either high-speed

or full-speed using software. In order to enable the high-speed operation for this module, the HSE

bit in SYSCFG should be set to 1. Changing the HSE bit should be done in the initial settings

immediately after a power-on reset or with the D+ line pull-up disabled (DPRPU = 0).

If high-speed mode has been enabled, this module executes the reset handshake protocol, and the

USB communication speed is set automatically. The results of the reset handshake can be

confirmed using the RHST bit in DVSTCTR.

If high-speed operation has been disabled, this module operates at full-speed.
