120	EXT9_IN_DATA(5)
119	EXT9_IN_DATA(4)		(8)(7......0) – Bits
118	EXT9_IN_DATA(3)		(0)(dddddddd) - Data byte
117	EXT9_IN_DATA(2)		(1)(XXXXXXX0) - EOP.
116	EXT9_IN_DATA(1)		(1)(XXXXXXX1) - EEP.
115	EXT9_IN_DATA(0)
			Bit 7 is the most significant bit of the data byte.
			Pull-up resistors (e.g. 4k7 Ω) should be
			connected to these inputs if External FIFO port
			9 is not being used.
124	EXT9_IN_FULL_N	Out	FIFO ready signal for external input port zero.			CMOS3V3
			When high there is space in the FIFO so it can
			be written to. When low the FIFO is full.
127	EXT9_IN_WRITE_N	In	Asserted (low) to write to the external input			CMOS3V3
			port zero FIFO.
			A pull-up resistor (e.g. 4k7 Ω) should be
			connected to this input if External FIFO port 9
			is not being used.
138	EXT10_OUT_DATA(8)	Out	Output data from external port number two			CMOS3V3
137	EXT10_OUT_DATA(7)		FIFO . Bit eight determines the type - data,
136	EXT10_OUT_DATA(6)		eop or eep. The encodings are defined as:
133	EXT10_OUT_DATA(5)
132	EXT10_OUT_DATA(4)		(8)(7......0) – Bits
131	EXT10_OUT_DATA(3)		(0)(dddddddd) - Data byte
130	EXT10_OUT_DATA(2)		(1)(XXXXXXX0) - EOP.
129	EXT10_OUT_DATA(1)
			(1)(XXXXXXX1) - EEP.
128	EXT10_OUT_DATA(0)
			Bit 7 is the most significant bit of the data byte.
139	EXT10_OUT_EMPTY_N	Out	FIFO ready signal for external output port one.			CMOS3V3
			When high the FIFO has data. When low the
			FIFO is empty.
142	EXT10_OUT_READ_N	In	Asserted (low) to read from the external output			CMOS3V3
			port one FIFO.
			A pull-up resistor (e.g. 4k7 Ω) should be
			connected to this input if External FIFO port 10
			is not being used.
151	EXT10_IN_DATA(8)	In	Input data to external port number two FIFO.			CMOS3V3
150	EXT10_IN_DATA(7)		Bit eight determines the type - data, eop or
149	EXT1-_IN_DATA(6)		eep. The encodings are defined as:
148	EXT10_IN_DATA(5)
147	EXT10_IN_DATA(4)		(8)(7......0) – Bits
