WAKETIME<10:8>: Wake-up Time Counted by SLPCLK bits
WAKETIME is an 11-bit value that is compared with the Main Counter (MAINCNT) to signal the time to
enable (wake-up) the 20 MHz main oscillator when the MRF24J40 is using the Sleep mode timers.
Default value: 0x00A. Minimum value: 0x001.
WAKETIME<7:0>: Wake Time Match Value bits
WAKETIME is an 11-bit value that is compared with the Main Counter (MAINCNT) to signal the time to enable
(wake-up) the 20 MHz main oscillator when the MRF24J40 is using the Sleep mode timers. Default value:
0x00A. Minimum value: 0x001.
