All signals available at this port, with one exception, are ex-
pressed as two’s complement values, ranging from –128
to +127 (80
H
to 7F
H
). The PN Matched Filter power output
values, available when the value in bits 3-0 of address 38
H
is set to either 1
H
or 8
H
, is an unsigned binary number,
ranging from 0 to 255 (0
H
to FF
H
).
The reset sequence that occurs when the receiver is dis-
abled will also reset the contents of address 38
H
to a value
of 0. If the RXTEST
7-0
bus is to be used to observe any
function other than the PN Matched Filter I and Q inputs,
then the appropriate value must be rewritten.
TXTEST (Pin 59)
Transmitter Test Output.
TXTEST provides access to 3
test points within the transmitter as shown in The pin out-
put is selected according to the state of the two least sig-
nificant bits of the address line, ADDR
1-0
and the assign-
ments shown in Table 5. Note that this method of
accessing the transmitter test points is completely different
than the method by which the receiver test points are ac-
cessed. The state of the other address lines does not af-
fect this function, and this function is always enabled. The
availability of TXTEST output signals is only supported for
TXIFCLK speeds less than 20 MHz; output with clock
speeds greater than 20 MHz will be indeterminate.
