Functional Explanation 6.1. Power States When VDD and VID are turned on from Vdd=OFF (0V) and Vid=OFF (0V), all registers in AK8963 are initialized by POR circuit and AK8963 transits to Power-down mode. All the states in the table below can be set, although the transition from state 2 to state 3 and the transition from state 3 to state 2 are prohibited. Table 6.1 State 1 6.2. VDD OFF (0V) VID OFF (0V) 2 3 OFF (0V) 2.4V to 3.6V 1.65V to 3.6V OFF (0V) 4 2.4V to 3.6V 1.65V to Vdd Power state OFF (0V). It doesn’t affect external interface. Digital input pins other than SCL and SDA pin should be fixed to “L”(0V). OFF (0V). It doesn’t affect external interface. OFF (0V). It doesn’t affect external interface. Digital input pins other than SCL and SDA pin should be fixed to “L” (0V). ON Reset Functions When the power state is ON, always keep Vid≤Vdd. Power-on reset (POR) works until Vdd reaches to the operation effective voltage (about 1.4V: reference value for design) on power-on sequence. After POR is deactivated, all registers are initialized and transits to power down mode. When Vdd=2.4 ~ 3.6V, POR circuit and VID monitor circuit are active. When Vid=0V, AK8963 is in reset status and it consumes the current of reset state (IDD4). AK8963 has four types of reset; (1) Power on reset (POR) When Vdd rise is detected, POR circuit operates, and AK8963 is reset. (2) VID monitor When Vid is turned OFF (0V), AK8963 is reset. (3) Reset pin (RSTN) AK8963 is reset by Reset pin. When Reset pin is not used, connect to VID. (4) Soft reset AK8963 is reset by setting SRST bit. When AK8963 is reset, all registers are initialized and AK8963 transits to Power-down mode. ShortDatasheet-E-01 - 11 - 2012/02 [AK8963] 6.3. Operation Modes AK8963 has following seven operation modes: (1) Power-down mode (2) Single measurement mode (3) Continuous measurement mode 1 (4) Continuous measurement mode 2 (5) External trigger measurement mode (6) Self-test mode (7) Fuse ROM access mode By setting CNTL1 register MODE[3:0] bits, the operation set for each mode is started. A transition from one mode to another is shown below. MODE[3:0]=“0001” Power-down mode MODE[3:0]=“0000” Single measurement mode Sensor is measured for one time and data is output. Transits to Power-down mode automatically after measurement ended. Transits automatically MODE[3:0]=“0010” MODE[3:0]=“0000” MODE[3:0]=“0110” MODE[3:0]=“0000” MODE[3:0]=“0100” MODE[3:0]=“0000” MODE[3:0]=“1000 MODE[3:0]=“0000” Continuous measurement mode 1 Sensor is measured periodically in 8Hz. Transits to Power-down mode by writing MODE[3:0]=“0000”. Continuous measurement mode 2 Sensor is measured periodically in 100Hz. Transits to Power-down mode by writing MODE[3:0]=“0000”. External trigger measurement mode Sensor is measured for one time by external trigger. Waits for next trigger after data is output. Transits to Power-down mode by writing MODE[3:0]=“0000”. Self-test mode Sensor is self-tested and the result is output. Transits to Power-down mode automatically. Transits automatically MODE[3:0]=“1111 MODE[3:0]=“0000” Fuse ROM access mode Turn on the circuit needed to read out Fuse ROM. Transits to Power-down mode by writing MODE[3:0]=“0000”. Figure 6.1 Operation modes When power is turned ON, AK8963 is in power-down mode. When a specified value is set to MODE[3:0], AK8963 transits to the specified mode and starts operation. When user wants to change operation mode, transit to power-down mode first and then transit to other modes. After power-down mode is set, at least 100ms(Twat) is needed before setting another mode.
