The CPU uses five-stage pipeline control to enable single-clock execution of address calculations, arithmetic
logic operations, data transfers, and almost all other instruction processing.
Other dedicated on-chip hardware, such as a multiplier (16 bits × 16 bits → 32 bits) and a barrel shifter (32
bits) contribute to faster complex processing.
The BCU starts a required external bus cycle based on the physical address obtained by the CPU. When an
instruction is fetched from external memory space and the CPU does not send a bus cycle start request, the
BCU generates a prefetch address and prefetches the instruction code. The prefetched instruction code is
stored in an instruction queue.
This is a 512/384/256/128 KB flash memory mapped to addresses 0000000H to 007FFFFH/0000000H to
005FFFFH/0000000H to 003FFFFH/0000000H to 001FFFFH.
It can be accessed from the CPU in one clock during instruction fetch.
This is a 40/32/16/8 KB RAM mapped to addresses 3FF5000H to 3FFEFFFH/3FF7000H to 3FFEFFFH
/3FFB000H to 3FFEFFFH/3FFD000H to 3FFEFFFH. It can be accessed from the CPU in one clock during
data access.
This controller handles hardware interrupt requests (NMI, INTP0 to INTP7) from on-chip peripheral hardware
and external hardware. Eight levels of interrupt priorities can be specified for these interrupt requests, and
multiplexed interrupt servicing control can be performed.
A main clock oscillator and subclock oscillator are provided and generate the main clock oscillation frequency

An internal oscillator is provided on chip. The oscillation frequency is 220 kHz (TYP). The internal oscillator
supplies the clock for watchdog timer 2 and timer M.
Six-channel 16-bit timer/event counter P (TMP), one-channel 16-bit timer/event counter Q (TMQ), and one-
channel 16-bit interval timer M (TMM), are provided on chip.
This timer counts the reference time period (0.5 s) for counting the clock (the 32.768 kHz subclock or the
