12.2. CIP-51 Register Descriptions
Following are descriptions of SFRs related to the operation of the CIP-51 System Controller. Reserved bits
should always be written to the value indicated in the SFR description. Future product versions may use
these bits to implement new features in which case the reset value of the bit will be the indicated value,
selecting the feature's default state. Detailed descriptions of the remaining SFRs are included in the sec-
tions of the data sheet associated with their corresponding system function.
SFR Definition 12.1. DPL: Data Pointer Low Byte
SFR Address = 0x82
SFR Definition 12.2. DPH: Data Pointer High Byte
SFR Address = 0x83
