WAKETIME<7:0>: Wake Time Match Value bits(1)

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.

Note 1:

Rule: WAKETIME > WAKECNT.

Reserved: Maintain as ‘0’

bit 2-0

WAKETIME<10:8>: Wake-up Time Counted by SLPCLK bits(1)

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.

Note 1: Rule: WAKETIME > WAKECNT.
