Table 8.
Only two PCF2113x registers, the Instruction Register (IR) and the Data Register (DR),
can be directly controlled by the microcontroller. Before internal operation, control
information is stored temporarily in these registers to allow interfacing to various types of
microcontrollers which operate at different speeds or to allow interfacing to peripheral
control ICs.
The instruction set for I
how these control and command bytes are embedded in the I
The PCF2113x operation is controlled by the instructions shown in
their execution time. Details are explained in subsequent sections.
