ZSSC3122 Datasheet
5.1.1 IDT Configuration Register (ZMDI_Config, EEPROM Word 02_HEX)
This register is loaded at power-on reset and upon exiting Command Mode using a Start_NOM command.

Description and Notes
0 = Update Mode
1 = Sleep Mode
Power Down Period: ^***
00_BIN = 0ms
01_BIN = 5ms
10_BIN = 25ms
11_BIN = 125ms
Scales the SOT TC Terms:
0 = Scale x 1
1 = Scale x 2
Multiply Gain_1 and Gain_2 by
0 = multiply by 1
1 = multiply by 4
011_BIN = locked
All other = unlocked
When EEPROM is locked, the internal charge pump
is disabled and the EEPROM can no longer be
programmed.
Note: If the EEPROM was accidentally locked, see
section 5 for instructions for unlocking it.
011_BIN = locked
All other = unlocked
When communication is locked, I²C™
communication will only respond to its programmed
address. Otherwise if communication is unlocked,
I²C™ will respond to any address.
001_BIN = I²C
011_BIN = SPI
100_BIN = PDM Capacitance (+ 2 alarms)
110_BIN = PDM Capacitance + Temperature (+ 1
alarm)
All other configurations are not allowed
See Table 3.8 for more details.
*** _{All time values shown are typical; for the worst case values, multiply by 1.1 (nominal frequency ±10%).}
