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 KB flash memory mapped to addresses 0000000H to 007FFFFH/0000000H to
005FFFFH/0000000H to 003FFFFH. It can be accessed from the CPU in one clock during instruction fetch.
This is a 60 KB RAM mapped to addresses 3FF0000H to 3FFEFFFH. It can be accessed from the CPU in one
clock during data access.
00283FFFH/00280000H to 0028FFFFH.
This controller handles hardware interrupt requests (NMI, INTP00 to INTP25) from on-chip peripheral
hardware and external hardware. Eight levels of interrupt priorities can be specified for these interrupt requests,
and multiplexed 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 AA (TAA), two-channel 16-bit timer/event counter AB (TAB), one-channel
16-bit timer/event counter T (TMT), and four-channel 16-bit interval timer M (TMM) are provided on chip. The
motor control function can be realized using TAB1 and TAA4 in combination.
