MEMORY ORGANIZATION
MCS3142 has 128 bytes of configuration data. In
general, the Configuration bytes can be divided into
three categories: those options related to the Classic
KEELOQ technology encoder, those options related to
the Ultimate KEELOQ technology encoder, and those
options related to the transmitter and device operation
shared by the two encoders.
