For more information concerning the TM2CON, CTCON, TM2IR and
the STE/RTE registers see IC20 handbook, chapter “80C51 family
hardware description”.
Port 4 can be read and written by software without affecting the
toggle, set and reset signals. At a byte overflow of the least
significant byte, or at a 16-bit overflow of the timer/counter, an
interrupt sharing the same interrupt vector is requested. Either one
or both of these overflows can be programmed to request an
interrupt.
All interrupt flags must be reset by software.
