K13 INT: Interrupt (Active Low)
This is the open drain, active low interrupt output. Four sources may cause the interrupt (refer
to Interrupt Handling of Functional Description for details).

Dn: Data Bus 7~0
In non-multiplexed host mode, these pins are the bi-directional data bus.
ADn: Address/Data Bus 7~0
In multiplexed host mode, these pins are the multiplexed bi-directional address/data bus.

In serial host mode, these pins should be grounded.

F4 MCn: Performance Monitor Configuration 4~0
13
F3 In hardware control mode, A4 must be connected to GND. MC[3:0] are used to select one
14
F2 transmitter or receiver of the channel 1 to 7 for non-intrusive monitoring. Channel 0 is used as
15
F1 the monitoring channel. If a transmitter is monitored, signals on the corresponding pins TTIPn
16
G3 and TRINGn are internally transmitted to RTIP0 and RRING0. If a receiver is monitored, signals
on the corresponding pins RTIPn and RRINGn are internally transmitted to RTIP0 and RRING0.
The clock and data recovery circuit in receiver 0 can then output the monitored clock to pin
RCLK0 as well as the monitored data to RDP0 and RDN0 pins. The signals monitored by cha-
nnel 0 can be routed to TTIP0/TRING0 by activating the remote loopback in this channel.
Performance Monitor Configuration determined by MC[3:0] is shown below. Note that if MC[2:0]
= 000, the device is in normal operation of all the channels.

An: Address Bus 4~0
When pin MODE1 is low, the parallel host interface operates with separate address and data
bus. In this mode, the signal on this pin is the address bus of the host interface.
