To make the MRF89XA device enter into Sleep mode,
certain control register values must be initialized. The
sequence to program the control registers for entering
into Sleep and Wake-up modes is as follows:
For Sleep mode:
1.
2.
3.
4.
EXAMPLE 3-1:
The MRF89XA device can wake up from any interrupt
activity.
For Wake-up mode perform any one the following task:
• Enter in TX/RX mode
• Enable CLKOUT
• Set the INT pin
EXAMPLE 3-2:
