36.3.40 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.
STOH/STOL is handled as a 16-bit (STO[15:0]) register in the USBF which consists of
STO[15:8] bits in STOH and STO[7:0] bits in STOL. Although STOH can be read directly STOL
is read via an 8-bit temporary register. Therefore, the registers should be read in the order of
STOH and STOL in byte units. STOL cannot be read singly.
