Type: E = EEPROM, R= Register, T = Trim data
Note: When using the SPI serial interface the register address bit A7 is also used for selecting write (A7= 0) or read (A7=1) operation. For
the I2C interface address bit A7 = 1.
Important note: All addresses presented in this document use 8-bit notation. The I2C bus device address
consists of 7 address bits and 8th LSB bit which selects between write (LSB=0) and read (LSB=1) operation. Thus
MAS6505 device address for write is EAHEX and for read EBHEX. In the SPI bus the register and EEPROM
addresses start with MSB bit (A7) which selects between write (MSB=0) and read (MSB=1) and which is followed
by 7 address bits. For example when using 8-bit address notation the Configuration register write and read
addresses via SPI bus are then 6EHEX and EEHEX respectively. In the I2C the A7 MSB address bit value is always
one (A7=1).
