24 address lines, 8- or 16-bit data I/O (separate busses or multiplexed bus)
Programmable automatic wait cycle insertion for each area
DMA controller (DMAC)
4 channels
Address space : 32 bits (4 Gbytes)
Transfer modes : Block transfer/burst transfer/demand transfer
Address update : Increment/decrement/fixed (increment/decrement step size of 1, 2, or 4)
Transfer data length : Selectable from 8-bit, 16-bit, 32-bit
Block size : 1 to 16
Number of transfers : 1 to 65535
Transfer requests
- Requests from software
- Interrupt requests from peripheral resources (interrupt requests are shared, including external interrupts)
Reload functions : Reload can be specified on all channels
Priority order : Fixed (ch.0 ch.1 ch.2 ch.3 ...) or round-robin
Interrupt requests : Interrupts can be generated for transfer complete, transfer error, and transfer interrupted.
Multifunction serial interface
Operation mode is selectable from UART/CSIO/I2C for each channel
UART
- Full-duplex double buffer
- Selectable parity on/off
- Built-in dedicated baud rate generator
- External clock can be used as a serial clock
- Error detection function for parity, frame and overrun errors
CSIO
- Full-duplex double buffer
- Built-in dedicated baud rate generator
- Overrun error detection function
I2C
- Supports both standard mode (Max 100 kbps) and Fast mode (Max 400 kbps)
- Some channels are 5 V tolerant
