Description
1…50 GND GND
Ground – these lines are the ground ref-
erence for all other signals
51..66 PB15…PB0 DATA I/O
PortB bidirectional data liness-PB15 is
the MSB, and PB0 is the LSB.
67 DOACK CONTROL I
Digital output Acknowledge lines – In
handshaking mode, DOACK carries
handshaking status information from the
peripheral.
68 DOREQ CONTROL O
Request line – In handshaking mode,
DOREQ carries handshaking control
information to peripheral.
69 DOTRIG CONTROL I
DO TRIG- can be used to control the
start of data output in all DO modes and
to control the stop of pattern generation
in pattern generation mode.
70…73 AUXDO3…0 DATA O
AUX DO 3…0 – can be used as extra
output data or can be used as extra
control signals.
85..100 PA15…PA0 DATA I/O
PortA bidirectional data liness-PA15 is
the MSB, and PA0 is the LSB.
82 DIACK CONTROL O
Digital input Acknowledge lines – In
handshaking mode, DIACK carries
handshaking status information to the
peripheral.
83 DIREQ CONTROL I
Request line – In handshaking mode,
DIREQ carries handshaking control
information from peripheral. In external
clock mode, DIREQ carries the external
clock input.
