16-bit programmable timer including watchdog timer and event counter functions, four channels of serial
interface, mobile access interfaces (one PHS, PDC, and HDLC channel each), input and I/O ports, and a clock
timer.
C33 Analog Block
The analog block consists of a 10-bit A/D converter with eight input channels.
C33 DMA Block
The DMA block is configured with two types of DMA controllers: HSDMA (High-Speed DMA) that has on-
chip registers for controlling DMA command information and IDMA (Intelligent DMA) that uses a memory
area for storing DMA command information.
