Re-
31.7.8 General-Purpose Timer 0 Control (Non-EHCI-Compliant) Register
The host/device controller driver can measure time-related activities using this timer register.
This register is not part of the standard EHCI controller. This register contains the control
for the timer and a data field can be queried to determine the running count value. This
timer has granularity on 1 us and can be programmed to a little over 16 seconds. There are
two modes supported by this timer, the first is a one-shot and the second is a looped count
that is described in the register table below. When the timer counter value transitions to 0,
an interrupt can be generated through the use of the timer interrupts in the USBTS and
USBINTR registers.

General-Purpose Timer Load Value. This field is the value to be loaded into the GPTCNT countdown timer
on a reset action. This value in this register represents the time in microseconds minus 1 for the timer
duration.
Example: for a one-millisecond timer, load 1000 Note: Max value is 0xFFFFFF or 16.777215 seconds.
