This bit is only active when the UTRDIS bit (U1CNFG2<0>) is set.
Unimplemented: Read as ‘0’
CNT7:CNT0: Start-Of-Frame Size bits;
Value represents 10 + (packet size of n bytes). For example:
0100 1010 = 64-byte packet
0010 1010 = 32-byte packet
0001 0010 = 8-byte packet
Unimplemented: Read as ‘0’
UTEYE: USB Eye Pattern Test Enable bit
1 = Eye pattern test enabled
0 = Eye pattern test disabled
UOEMON: USB OE Monitor Enable bit
1 = OE signal active; it indicates intervals during which the D+/D- lines are driving
0 = OE signal inactive
Unimplemented: Read as ‘0’
USBSIDL: USB OTG Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Unimplemented: Read as ‘0’
PPB1:PPB0: Ping-Pong Buffers Configuration bit
11 = EVEN/ODD ping-pong buffers enabled for Endpoints 1 to 15
10 = EVEN/ODD ping-pong buffers enabled for all endpoints
01 = EVEN/ODD ping-pong buffer enabled for OUT Endpoint 0
00 = EVEN/ODD ping-pong buffers disabled
