Data Bus 16_8. Selects between 8- and 16-bit data transfers.
1–16-bit data path operation enabled. CLK = 30 MHz.
0–8-bit data path operation enabled. When Uni_Bidi = 0, D[8:15] are unde-
fined. When Uni_Bidi =1, D[0:7] are valid on RxValid and D[8:15] are valid on
TxValid. CLK = 60 MHz
Note that 16-bit operation is only an option for a HS/FS transceiver imple-
mentation.
Crystal Input. Connect this signal to a 24-MHz parallel-resonant, funda-
mental mode crystal and 20-pF capacitor to GND.
It is also correct to drive XTALIN with an external 24-MHz square wave de-
rived from another clock source.
Crystal Output. Connect this signal to a 24-MHz parallel-resonant, funda-
mental mode crystal and 30-pF (nominal) capacitor to GND. If an external
clock is used to drive XTALIN, leave this pin open.
Driving this pin HIGH enables the unidirectional mode when the 8-bit
interface is selected. Uni_Bidi is static after power on reset (POR).
