8-level Interrupt Controller
The Interrupt Controller controls interrupt requests from
each internal peripheral I/O (31 sources) by using eight pri-
ority levels assigned to each interrupt source, including in-
terrupts disabled. In addition to these interrupts, it handles
System Break Interrupt (SBI), Reserved Instruction Excep-
tion (RIE), and Address Exception (AE) as nonmaskable in-
terrupts.
Wait Controller
The Wait Controller supports access to external devices.
For access to an external extended area of up to 1 Mbytes
(during external extended or processor mode), the Wait
Controller controls bus cycle extension by inserting one to
four wait cycles or using external WAIT signal input.

Realtime Debugger (RTD)
The Realtime Debugger (RTD) provides a function for ac-
cessing directly from the outside to the internal RAM. It uses
a dedicated clock-synchronized serial I/O to communicate
with the outside.
Use of the RTD communicating via dedicated serial lines al-
lows the internal RAM to be read out and rewritten without
having to halt the CPU.
