3.
Mounted Memory
4.
DMAC (DMA Controller)
Capable of simultaneous operation of up to five channels (three channels for external
→external operation)
Three transfer sources (external pin, internal peripheral, software) selectable by software. (Transfer can be
started from UART0/1/2.)
Addressing using 32-bit full addressing mode (increment, decrement, fixed)
Transfer modes (demand transfer, burst transfer, step transfer, block transfer)
Support for fly-by transfer (between external I/O and memory)
Selectable transfer data size: 8, 16, or 32-bit
Multi-byte transfer enabled (by software)
DMAC descriptor in IO areas (200H to 240H, 1000H to 1024H)
5.

Four channels of 16-bit reload timer (including one for REALOS):
Internal clock frequency selectable from among divisions by 2/8/32 (division by 64/128 selectable only for
channel 3)
16-bit free-running timer: 1 channel.
Output compare module: 8 channels. Input capture module: 4 channels
16-bit PPG timer ch6
7.
UART
UART Full duplex double buffer 5 channel
Selectable parity On/Off
Asynchronous (start-stop synchronized) or CLK-synchronous communications selectable
