Table 12 Input Data Functions
Serial Data Input/Output Mode Selection
The LC72146 use the CCB (computer control bus) serial data format. The first eight bits form the address, shown in
Figure 6, used to select the mode of operation as shown in Table 13.

Input port data
Bits I1 to I7 reflect the data latched into each input port when the device changes to data output mode.
I6 and I7 are zero when the corresponding port is a counter input. I1 to I5 correspond to the I/O-1 to I/O-5
ports, and I6 and I7, to the HCTR/I-6 and LCTR/I-7 inputs, respectively.
Counter contents
Bits C0 to C19 are the latched contents of the 20-bit binary counter. C19 is the MSB. C0 is the LSB.
