Digital Basic Type A / Communications Type A Block xx Input Register

The Digital Basic Type A / Communications Type A Block

xx Input Register (DBA00IN-DCA07IN) consists of 4 bits

[3:0] to select the block input clock and 4 bits [7:4] to

select the primary data/enable input. The actual usage of

the input data/enable is function dependent.

Digital Basic Type A Block 00 Input Register

(DBA00IN, Address = Bank 1, 21h)

Digital Basic Type A Block 01 Input Register

(DBA01IN, Address = Bank 1, 25h)

Digital Basic Type A Block 02 Input Register

(DBA02IN, Address = Bank 1, 29h)

Digital Basic Type A Block 03 Input Register

(DBA03IN, Address = Bank 1, 2Dh)

Digital Communications Type A Block 04 Input Register

(DCA04IN, Address = Bank 1, 31h)

Digital Communications Type A Block 05 Input Register

(DCA05IN, Address = Bank 1, 35h)
