All bits defined as reserved must be written by software with 0s, for preserving
future compatibility. When read, any reserved bit returns 0. It is good software
practice to use complete mask patterns for setting or testing bit fields
individually within a register.
Description
OTG revision number: this 8-bit field indicates the revision number of the
current OTG controller, in binary-coded digital (BCD), with the major
revision number in bits 7−4, and the minor revision number in bits 3−0.
This value is hardware fixed.
0x10: Revision 1.0
0x11: Revision 1.1
0x12: Revision 1.2
0x13: Revision 1.3
0x14: Revision 1.4
0x15: Revision 1.5
0x16: Revision 1.6
....
0xF2: Revision 15.2
This read-only register reflects the OTG controller revision number.
