9.2 Operation Principle
Figure 8. Operation Principle
START-UP.
After power up and after applying a soft reset (Reg 0Fh [1]) or hardware reset (RESETn input, LOW pulse >100ns), N40P112 enters the START-
UP state. During this state the internal registers are loaded with their reset values. Then the N40P112 will perform one measurement and
switches automatically into the WAIT state.
MEASURE.
The hall element data are measured, x/y coordinates are calculated and available in registers 10h and 11h after Tconv = 450µs max.
SET INTERRUPT.
The INTn output is set, depending on the interrupt mode configured in the control register Reg 0Fh [2] and Reg 0Fh [3]
WAIT.
The module is now in waiting status. A new measurement will occur depending on the power mode (Reg 0Fh [7] Idle = 0 or 1) and the Timebase
Reg 0Fh [6:4]
