JUMP

HALT
R/W
State machine commands for loading EEPROM data after reset. (see extended EPROM configuration)
HALT
Writing a 1 to this bit stops the reading of EEPROM data.
SKIP
Writing a 1 to this bit forces the next EEPROM read cycle to occur at the address held in the
Configuration Control (n) register, where "n" is the value held in the Configuration Index Regis-
ter (43h)
JUMP
Writing a 1 to this bit forces the next EEPROM access to occur at the address held in registers
40h and 40h.

R/W
This contains the DIP switch status at reset. (see extended EPROM configuration) The value of this register selects
the appropriate Configuration register when the SKIP command is executed.
Reserved Registers (44h - FEh)
These registers are reserved and return a value of 00h when read.
