1: set high to clear state.
0: set low to exit clear state (default).
RT: Clear frame length error for Bulk Out.
1: set high to enter clear state.
0: set low to exit clear state (default).
PRTE: External Phy Reset pin Tri-state Enable.
1: Enable, i.e., the external PHYRST_N pin is tri-stated (default). This allows the PHYRST_N pin’s active level to
be controlled by external pulled-up (active high during power-on) or pulled-down resistor (active low during
power-on).
0: Disabled, i.e., the external PHYRST_N pin’s level is driven by either PRL bit or internal “USB RESET” based on
the setting in SCPR bit in Flag byte of EEPROM.
PRL: External Phy Reset pin Level. When SCPR bit = 1 and PRTE = 0, this bit controls the output level of external
PHYRST_N pin.
1: Set to high (default).
0: Set to low.
BZ: Force Bulk In to return a Zero-length packet.
1: Software can force Bulk In to return a zero-length USB packet.
0: Normal operation mode (default).
IPRL: Internal Phy Reset control. When SCPR bit = 1, this bit acts as reset signal of internal Ethernet Phy.
1: Internal Ethernet Phy is in operating state.
0: Internal Ethernet Phy in reset state (default).
IPPD: Internal Ethernet Phy Power Down control.
1: Internal Ethernet Phy is in power down mode (default).
0: Internal Ethernet Phy is in operating mode.

PSEL: Phy Select, when ASEL = 0 (manually select the Phy to operate)
1: Select embedded 10/100 Ethernet Phy (default).
0: Select external Phy, which is attached to the MII interface
ASEL: Auto Select or Manual Select
1: Automatically select based on link status of embedded 10/100 Ethernet Phy (default).
0: Manually select between the embedded 10/100 Ethernet Phy and the external one.
RR: Clear frame length error for Bulk In.
