25.3.39 Timer Register (TMRH/TMRL)
TMRHWMRL is a 16-bit timer which is operated with a peripheral clock φ. Measuring the SOF
packet reception interval enables the SOF packet break to be detected.
The timer is operated, stopped, and cleared according to the settings of the control register 1
(CTLR1).
Note: The timer register is used as a 16-bit register which consists of upper byte TMRH and lower
25.3.40 Set Time Out Register (STOH/STOL)
STOH/STOL specifies the time out value of the timer register. When the count value of the timer
register reaches the specified time out value, the time out interrupt flag in the interrupt flag register
4 is set.
Note: The timer register is used as a 16-bit register which consists of upper byte STOH and lower

TMRL in USBF. TMRH can be read directly, but TMRL is read via an 8-bit temporary
register. Therefore, the registers should be read in the order, TMRH and TMRL, in byte
units. TMRL cannot be read singly.
STOL in USBF. STOH can be read directly, but STOL is read via an 8-bit temporary
register. Therefore, the registers should be read in the order, STOH and STOL, in byte
units. TMRL cannot be read singly.
