Notes: 1. The reset value for UDPHS_EPTCTL0 is 0x0000_0001.
2. The addresses for the UDPHS Endpoint registers shown here are for UDPHS Endpoint0. The structure of this group of reg-
isters is repeated successively for each endpoint according to the consecution of endpoint registers located between 0x120
and
0x1FC .
3. The addresses for the UDPHS DMA registers shown here are for UDPHS DMA Channel1. (There is no Channel0) The
structure of this group of registers is repeated successively for each DMA channel according to the consecution of DMA reg-
isters located between 0x320 and 0x36C.
