CONVERSION RESULT REGISTERS (E7…E9HEX
)
After measuring external sensor, temperature or
VDD level the 24-bit conversion result is stored into
three Conversion result register addresses
E7…E9HEX. The MSB (most significant byte) is at
E7HEX, ISB (intermediate significant byte) at E8HEX
and LSB (least significant byte) at E9HEX
.
EEPROM STATUS REGISTER (EA/6AHEX
)
The EEPROM status register (EA/6AHEX) indicates
if the stored EEPROM byte is corrupted. The
register is updated after each EEPROM data byte
read command. See table 7 below. The ERROR bit
tells if a data error has been detected (ERROR=1).
The DED bit tells if two or more bit errors have
been detected (DED=1). The EEPROM can correct
internally only single bit errors i.e. when ERROR=1
and DED=0. The read EEPROM data byte is
corrupted if ERROR=DED=1. The six lowest bits
have value 0.
Table 7. MAS6503 EEPROM status register (EA/6AHEX). Only bits (7:6) are used.

REGULATOR OUTPUT VOLTAGE CONTROL REGISTERS (EB/6BHEX
)
control register (EB/6BHEX). In the register only two
most significant bits are in use. See table 8.
When enabled the internal voltage regulator output
voltage is defined by the Regulator output voltage
