The main program continually checks the registers of the sensor to see
if any XY movement happened. If any XY movement is detected, it gets
the X and Y displacements from the sensor registers, puts them in the
FIFO buffer and sets the corresponding flags. For every ms timer tick, it
checks the Z movement and the buttons’ status. If new mouse data has
been detected, JB8 will initiate the RF data transmission through the
baseband RFW-D100 IC.
Apart from serving the interrupt events from the baseband D100 IC
during normal operation, IRQ serves as the periodical wakeup signal
when JB8 is in sleep mode. The JB8 must check whether there is any
new movement or if the buttons’ status changed. IRQ ISR firmware will
determine what appropriate actions must be taken.
