Features of Internal Peripheral I/Os
Functional Block
Features
DMA
10-channel DMA
Supports data transfer between internal peripheral I/Os, between internal RAMs,
and between internal peripheral I/O and internal RAM
Capable of fast DMA transfer when used in combination with internal peripheral I/O
Capable of cascaded operation between DMA channels (starting DMA transfer on
a channel at the end of transfer on another)
Timer
26-channel multifunction timers
16 channels of 16-bit output related timers, 6 channels of 16-bit input related
timers, and 4 channels of 32-bit input related timers
Flexible timer configuration is possible by interconnecting each timer channel
A-D converter
One 8-channel A-D converter and one 4-channel A-D converter, both capable of
10-bit resolution
Supports comparator mode
Can generate an interrupt or start DMA transfer at completion of A-D conversion
Can monitor pin levels on a total of 20 channels (with reduced accuracy, however)
Serial I/O
8-channel serial I/O
Can be set for clock-synchronized serial I/O or UART
Capable of fast data transfer at 2 Mbits/second during clock-synchronized mode or
156 Kbits/second during UART mode
Real-time debugger
Can rewrite/monitor the internal RAM by command input from the outside,
independently of the CPU
Comes with dedicated clock-synchronized serial port
Interrupt controller
Controls interrupt requests from internal peripheral I/Os
Eight priority levels including interrupt-disabled state
Wait controller
Controls wait state when accessing external extended area
Inserts 1 to 4 wait cycles by software setting + extends wait period by external
____
WAIT signal input
Clock PLL
Multiply-by-4 clock generating circuit
CPU clock of maximum 40 MHz (CPU, internal ROM, and internal RAM access)
Internal peripheral clock of maximum 20 MHz (peripheral module access)
Maximum external input clock frequency of 10.0 MHz
D-A converter
Two channels of 8-bit resolution D-A converters
D-A0 converter: D-A output, successive data output function, 256-byte output
buffer available
D-A1 converter: D-A output only
PD Controller
Two blocks of PD sensor-accommodating timers and various arithmetic circuits for
position predictive operation
16-bit input measurement timer: 4 channels; 16-bit input related timer: 4 channels
When not using the PD circuit, the above timers can be used as input
measurement timers or input event counters
CAN
Two blocks of CAN modules, each with 16-channel message slots
JTAG
Boundary scan function, Mitsubishi original SDI debug function included
