UART interface
UARTTX, UARTRX, UARTRTS, and UARTCTS form a conventional asynchronous data serial port. The interface is designed
to operate correctly when connected to other UART devices such as NS16550A. The signaling levels are 0V and 3.3V. The
interface is programmable over a variety of bit rates. It supports many configurations such as no, even or odd parity, one or two
stop bit, number of bit in a frame, break conditions, and hardware flow control on or off. The maximum UART data rates is
1.8Mb/s. Two-way hardware control is implemented by UARTRTS and UARTCTS. If input UARTCTS signal becomes high,
transmission will be stopped, else it will be continued. If internal UART FIFO will be full, output UARTRTS signal becomes
high, else becomes low.
Flash Card interface
PT8R1202 supports two types of flash card such as SmartMedia™ flash devices and MMC or SDCard flash devices. This flash
card devices are small removable cards that contain one or two NAND Flash devices. Alternatively, the system designer can use
non-removable NAND flash chips. PT8R1202 supports hardware interface logic for SmartMedia™ devices, but only supports
software firmware using GPIO for MMC or SDCard. The SmartMedia™ electrical interface uses an 8-bit data/address bus and
6-bit control lines. PT8R1202 supports up to 4GB SmartMedia™ devices.
