This bit indicates that the USB97C100 supports 12Mbps USB
data rates. This bit must be set to a one ‘1’ for normal
operation.
1 = Resets the SIE
1 = Clears FRAMEL and Bit 0 through 2 of FRAMEH
Extended Frame Count Enable. Expands the Frame count
from 11 bits to 16 bits for 8051 use.
0 = bits 7-3 of FRAMEH are driven to 0.
1 = Bits 7-3 of FRAMEH count 1-0 transitions of bit 2 in
FRAMEH.
1 = Forces the SIE into USB Suspend Mode. The MCU must
determine that Suspend must be entered.
1 = Forces the SIE to transmit Resume signaling on the line.
1 = Indicates Resume signaling has been detected on the line
while in the Suspend State. This signal causes a Resume
Power Management interrupt).
1 = Indicates that the USB line is being reset. Asserted when
SE0 is present on the bus for 32 or more 12Mbps bit times.
This causes a USB_RESET Power management interrupt.
