User manual
9.2.1 USB Clock Control register (USBClkCtrl - 0xFFE0 CFF4)
9.2.2 USB Clock Status register (USBClkSt - 0xFFE0 CFF8)
9.2 Clock control registers
Table 294. USB Port Select register (USBPortSel - address 0xFFE0 C110) bit description
This register controls the clocking of the USB Device Controller. Whenever software
wants to access the device controller registers, both DEV_CLK_EN and AHB_CLK_EN
must be set. The PORTSEL_CLK_EN bit need only be set when accessing the
USBPortSel register.
The software does not have to repeat this exercise for every register access, provided that
the corresponding USBClkCtrl bits are already set. Note that this register is functional only
when the PCUSB bit of PCONP is set; when PCUSB is cleared, all clocks to the device
controller are disabled irrespective of the contents of this register. USBClkCtrl is a
read/write register.
Table 295. USBClkCtrl register (USBClkCtrl - address 0xFFE0 CFF4) bit description
This register holds the clock availability status. The bits of this register are ORed together
to form the USB_NEED_CLK signal. When enabling a clock via USBClkCtrl, software
should poll the corresponding bit in USBClkSt. If it is set, then software can go ahead with
the register access. Software does not have to repeat this exercise for every access,
provided that the USBClkCtrl bits are not disturbed. USBClkSt is a read only register.
