mode. Furthermore, a user can write 0 into USB_ATTR[4] to turn off PHY under special
circumstances like suspend to save power.
There is 512 bytes SRAM in the controller and the 6 endpoints share this buffer. The user shall
configure each endpoint’s effective starting address in the buffer segmentation register before the
USB function active. The BUFFER CONTROL block is used to control each endpoint’s effective
starting address and its SRAM size is defined in the MXPLD register.
Figure 5-12 depicts the starting address for each endpoint according the content of BUFSEG and
MXPLD registers. If the BUFSEG0 is programmed as 0x08h and MXPLD0 is set as 0x40h, the
SRAM size of endpoint 0 is start from USB_BA+0x108h and end in USB_BA+0x148h. (Note: the
USB SRAM base is USB_BA+0x100h).
BUFSEG0 = 0x008
BUFSEG1 = 0x048
BUFSEG2 = 0x088
BUFSEG3 = 0x100
