11.3.2. Normal Mode
There are the eight Modes in Normal Mode.
<Normal Mode (CAD0 pin= “L” or CAD1 pin= “L”)>
(1) Power down Mode
(2) Stand-by Mode
(3) Single shot Mode
(4) Continuous Mode 0
(5) Continuous Mode 1
(6) Continuous Mode 2
(7) Continuous Mode 3
(8) EEPROM access Mode
Power down Mode:
The all circuits are powered down for saving the current consumption.
PDN= “H”
PDN= “L”
[AK9750]
Stand-by
Mode
EMODE [2:0]= “010”
EMODE [2:0]= “000”
Automatic shift
Single shot Mode:
The measurement is done, and Saving the data on the
register. Stand-by Mode is automatically selected after
reading data.
EMODE [2:0]= “100” Continuous Mode0:
EMODE [2:0]=“000” ^{Measurement is automatically repeated.}
EMODE [2:0]= “101”
EMODE [2:0]= “000”
Continuous Mode 1:
Measurement is automatically repeated in intermittent manner
(Measurement time: Wait time= 1:1). The data updating period
is eight times longer than Continuous Mode 0.
EMODE [2:0]= “110”
EMODE [2:0]= “000”
Continuous Mode 2:
Measurement is automatically repeated in intermittent manner
(Measurement time: Wait time= 1:3). The data updating period
is twice longer than Continuous Mode 1.
EMODE [2:0]= “111”
EMODE [2:0]= “000”
Continuous Mode 3:
Measurement is automatically repeated in intermittent manner
(Measurement time: Wait time= 1:7). The data updating period
is twice times longer than Continuous Mode 2.
EEPMODE= “1” and
EMODE [2:0]= “001”
EMODE [2:0]= “000”
EEPROM Access Mode:
EEPROM rea/write circuit is on . EEPROM can be accessed
only in this Mode.
