TSF Timer
This register works in conjunction with the register at address 0x52 to
construct a 32-bit microsecond timer used for time stamps in received frames
and beacon transmissions.

TSF Timer
This register works in conjunction with the register at address 0x50 to
construct a 32-bit microsecond timer used for time stamps in received frames
and beacon transmissions.

TSF Comparator 1
This register contains the least-significant 16 bits of a 24-bit TSF timer value.
This register works in conjunction with the register at address 0x5A. The 16
bits of the TSF Comparator 1 register and the 8-bits of the TSF Comparator 2
register comprise the 24-bit TSF comparator value.
0x5A
16
TSF Comparator 2
This register contains the most-significant 8 bits of a 24-bit TSF timer value.
This register works in conjunction with the register at address 0x58. The 16
bits of the TSF Comparator 1 register and the 8-bits of the TSF Comparator 2
register comprise the 24-bit TSF comparator value. This 8-bit value is
contained in the lower 8 bits of this register. The upper 8 bits are reserved.
0x60
16
Add TSF Time
Hardware uses the lower 10 bits of this register to determine the length of
time that the TSF timer is disabled. This value can be modified by software.
0x64
16
NAV Timer
This 16-bit register contains a 1-s resolution timer that maintains the virtual
carrier sense mechanism. The timer is automatically loaded by the MAC but
can be modified by software.
0x66
16
Backoff Timer
This register is loaded automatically by the MAC from transmit frame header
structures. If a backoff condition occurs, the counter begins decrementing
until it reaches zero.
0x68
16
Response Timer
Contains a timeout value, in increments of 32 s, after which the MAC aborts
the transmit frame if it does not receive an acknowledgment.
0x6A
16
Tick Timer
Sets the interval time in milliseconds at which interrupts are generated.
0x6C
16
Timer Control
Contains enable and status information for each of the timers in the MAC
control register group.
0x6E
16
Slot Time
Contains the value used to determine the length of slots required for random
backoff.
