11 / 552 page W90P710CD/W90P710CDG Publication Release Date: September 19, 2006 - 11 - Revision B2 When reach middle and end address of destination address, a DMA_IRQ is requested to CPU automatically Smart Card Host Interface (SCHI) ISO-7816 compliant PC/SC T=0, T=1 compliant 16-byte transmitter FIFO and 16-byte receiver FIFO FIFO threshold interrupt to optimize system performance Programmable transmission clock frequency Versatile baud rate configuration UART-like register file structure General-purpose C4, C8 channels SD Host Interface Directly connect to Secure Digital (SD, MMC) flash memory card. Supports DMA function to accelerate the data transfer between the internal buffer, external SDRAM, and flash memory card. Two 512 bytes internal buffers are embedded inside the controller. No SPI mode. KeyPad Scan Interface Scan up to 16 rows by 8 columns with an external 4 to 16 decoder and 4 rows by 8 columns array without auxiliary component Programmable debounce time One or two keys scan with interrupt and three keys reset function. Wakeup CPU from IDEL/Power Down mode PS2 Host Interface APB slave consisted of PS2 protocol. Connect IBM keyboard or bar-code reader through PS2 interface. Provide hardware scan code to ASCII translation Power management Programmable clock enables for individual peripheral IDLE mode to halt ARM Core and keep peripheral working Power-Down mode to stop all clocks included external crystal oscillator. Exit IDLE by all interrupts Exit Power-Down by keypad,USB device and external interrupts |
