Unimplemented data memory locations, read as ‘0’.
Note 1: Not a physical register.
2: CRDAT<3:0> registers are KEELOQ hardware peripheral related registers and require the execution of the
“KEELOQ® Encoder License Agreement” regarding implementation of the module and access to related
registers. The “KEELOQ® Encoder License Agreement” may be accessed through the Microchip web site
located at www.microchip.com/KEELOQ or by contacting your local Microchip Sales Representative.
