Attribute
I/O, T.S.
When SPI port is enabled, this signal is the select input line for
that port. When this port is disabled, this signal may be used to
any available alternate function for PD19. In fact, for the ADS
application using as GPIO output pin.
I/O, T.S.
When SPI port is enabled, this signal is SPI clock output line for
that port. When this port is disabled, this signal may be used to
any available alternate function for PD18.
I/O, T.S.
When SPI port is enabled, this signal is master output line for that
port. When this port is disabled, this signal may be used to any
available alternate function for PD17.

I
Chip-select 2 input for HDI16 port. Present as well as at P4
connector.
I
Chip-select 1 input for HDI16 port. Present as well as at P4
connector.
I
When the HDI16 is programmed to interface to a single data
strobe host bus, this pin is the read/write input (HRW). When the
HDI16 is programmed to interface to a double data strobe host
bus, this pin is the read data strobe Schmitt trigger input (HRD).
Present as well as at P4 connector.
I
When the HDI16 is programmed to interface to a single data
strobe host bus, this pin is the data strobe Schmitt trigger input
(HDS). When the HDI16 is programmed to interface to a double
data strobe host bus, this pin is the write data strobe Schmitt
trigger input (HWR). Present as well as at P4 connector.
MSC8101's Port D7 Parallel I/O line. May be used to any of its
available functions
-
Not connected
I
ATM Receive Clock Out Disable. When active (H), the ATMRCLK
output, on pin C29 of this connector, is Tri-stated. When either not
connected or driven low, ATMRCLK on pin C29, is enabled. This
provides
communication tools.
I
Host tool present detect. Disable Host Interface with active low
(GND) for not compatible external tools.
P
5V Supply. Connected to ADS's 5V VCC plane. Provided as
power supply for external tool. For allowed current draw, see
TABLE 7-1. "Off-Board Application Maximum Current
Consumption" on page 66
I/O, T.S.
ATM Transmit Enabled (L). When this signal is asserted (Low),
while the ATM port is enabled and ATMTFCLK is rising, an octet
of data, ATMTXD(7:0), is written into the transmit FIFO of the
PM5350. When the ATM port is disabled, this line may be used
for any available function of PA31.
