23.4.1
This section describes the register operations that are necessary to the initial settings of this
module, and the registers necessary for power consumption control.
(1)
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
(2)
This module can select the host controller function or function controller function using the
DCFM bit in SYSCFG.
(3)
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.
