Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-0
MAINCNT<7:0>: Main Counter bits
Main counter is a 26-bit counter. Together with the remain counter times events: Beacon Interval (BI)
and inactive period for beacon-enabled devices and Sleep interval for nonbeacon-enabled devices.
Units: SLPCLK.(1)
Note 1: Sleep Clock (SLPCLK) period depends on the Sleep Clock Selection (SLPCLKSEL) RFCON<7:6> and
Sleep Clock Divisor (SLPCLKDIV) CLKCON<4:0> bits.
