BLOCK CONFIGURATION
2.1
BUS CONTROL UNIT (BCU)
The BCU performs control of the main bus. The BCU starts the necessary internal/external bus cycle on the basis of
the physical address obtained from the execution unit (EXU).
2.2
EXECUTION UNIT (EXU)
The EXU controls address calculation, arithmetic and logical operations, data transfer, etc., by means of a microprogram
(firmware for controlling the microsequencer on the basis of decoded op code). The EXU contains 512 bytes of RAM
(corresponding to the register file space).
2.3
INTERRUPT CONTROLLER (INTC)
The INTC services hardware interrupt requests generated by on-chip peripheral hardware and interrupt requests
generated externally with vectored interrupts, bank switching, or macro service. It can also control the programmable 4-
level interrupt priority order, and can also perform multiprocessing control for interrupt.
2.4
DMA CONTROLLER (DMAC)
The DMAC is a general-purpose DMA controller, capable of handling the 16M-byte memory space in a linear fashion.
Operating modes comprise memory-to-memory transfer mode, intelligent DMA (ring buffer method and counter control
method) mode, next address specification mode, and 2-channel operation.
2.5
UART/CLOCKED SERIAL INTERFACE (UART/CSI)
This block supports the asynchronous interface (UART) in which data synchronization is achieved by means of start/
stop bits, and the clocked serial interface (CSI), allowing either to be used.
For the clocked serial interface there is a further choice of serial bus interface mode (SBI) or 3-wire serial I/O mode.
2.6
PARALLEL INTERFACE UNIT (PIU)
This performs input/output using strobe signal synchronization in 8-bit units, and supports the Centronics interface and
general-purpose parallel data communication functions.
2.7
A/D CONVERTER UNIT (8-BIT A/D)
This is an A/D converter with 4 analog inputs, and provided with 4 A/D conversion result registers.
2.8
TIMER/COUNTER UNIT (TCU)
The timer/counter unit incorporates a 16-bit timer/counter, and can be used as an interval timer, free-running counter,
or event counter.
2.9
PWM (PULSE WIDTH MODULATION) UNIT (PWM)
An 8-bit precision PWM (pulse width modulation) signal output function.
2.10 WATCHDOG TIMER (WDT)
The WDT incorporates an 8-bit watchdog timer for detection of inadvertent program looping, system errors, etc. The
WDTOUT pin is provided to give external notification of the generation of watchdog timer interrupts.
2.11 PORTS (PORT)
53 port pins are provided, allowing port pin and control pin functions to be selected.
2.12 REAL-TIME OUTPUT PORT (RTOP)
This is a real-time output port which uses an interrupt from timer 0 as a trigger. It can output the contents of the 8-bit
buffer register at programmable intervals in 4-bit or 8-bit units.
