The USB Controller is equipped with a free-running timer
driven by a clock one-sixth the resonator frequency. Bits 0
through 7 of the counter are readable from the read-only Timer
Register located at I/O address 0x23. The Timer Register is
cleared during a Power-On Reset and whenever Suspend
On-Chip Timer
mode is entered.
Figure 6-5
illustrates the format of this
register and
Figure 6-6
is its block diagram.
With a 6 MHz resonator, the timer resolution is 1
μ
s.
The timer generates two interrupts: the 128-
μ
s interrupt and
the 1.024-ms interrupt.
