DAT_VP_RX, SE0_VM_TX, RCV
DAT_VP_RX, SE0_VM_TX and RCV provide the data
transfer interface between the system controller and
MIC2555. RCV is an output only pin, supplying the
output of a differential receiver monitoring the D+, D-
pins, while DAT_VP_RX, SE0_VM_TX are bi-directional
(I/O) pins and change function in accordance with
different USB and UART mode selections.
In UART mode, DAT_VP_RX and SE0_VM_TX are the
primary data transmit and receive pins.
In USB mode, the setting of the dat_se0 determines their
action, as described in the tables below.
OE_INT/
The “output enable – interrupt bar” (OE_INT/) pin has
three modes of operation, shown in the table below.
Suspend modes are controlled by the oe_int_en bit
found in Control Register 1.
