potential problems which may occur if a carry from the lower 8 bits
to the upper 8 bits occurs between the times that both halves of the
counter are read. However, note that a subsequent start counter
command will cause the counter to begin a new count cycle using
the values in CTUR and CTLR.
IVR – Interrupt Vector Register
This register contains the interrupt vector. The register is initialized
to H‘0F’ by RESET. The contents of the register are placed on the
data bus when the DUART responds to a valid interrupt
acknowledge cycle.
