FIRMWARE TIMER SETUP
The ADF7023-J wakes up from the PHY_SLEEP state at the rate
set by the WUC. A firmware timer, implemented by the on-chip
processor, can be used to count the number of hardware wake-ups
and generate an interrupt to the host processor. Thus, the
ADF7023-J can be used to handle the wake-up timing of the
host processor, reducing overall system power consumption.
To set up the firmware timer, the host processor must set a value
in the NUMBER_OF_WAKEUPS_IRQ_THRESHOLD[15:0]
registers (Address 0x104 and Address 0x105). This 16-bit value
represents the number of times the device wakes up before it

interrupts the host processor. At each wake-up, the ADF7023-J
increments the NUMBER_OF_WAKEUPS[15:0] registers
(Address 0x102 and Address 103). If this value exceeds the value
set by the NUMBER_OF_WAKEUPS_IRQ_THRESHOLD[15:0]
registers, the NUMBER_OF_WAKEUPS[15:0] value is cleared
to 0. At this time, if the INTERRUPT_NUM_WAKEUPS bit in
the INTERRUPT_MASK_0 register (Address 0x100) is set, the
device asserts the IRQ_GP3 pin and enters the PHY_OFF state.
