CONFIGURATION REGISTERS (CFR)
Programming the configuration registers (CFR) in the CPU sets the SOC-3000 pin functions.
The CFR registers include control and configuration registers that provide the interface
between the CPU and the other on-chip peripherals, such as the keyboard, LED and LCD
controllers and input/output ports. Each peripheral operates as designated in the CFR
registers, where each register may be programmed to perform alternative functions. (See
“Examples of Pin Configuration Programming”, on page 85).
The complete CFR-register bit assignment for all peripherals and input/output and
corresponding PLCC-84 pins are given on the following pages in Table 32.
