User Time Interval Select Register
User code writes the required time interval to this register. When the 8-bit interval counter is equal
to the time interval value loaded in the INTVAL SFR, the TII bit (TIMECON.2) bit is set and
generates an interrupt if enabled. (See IEIP2 SFR description under Interrupt System later in this
data sheet.)
