I/O Model Reference 109

Clock Bit Rate for 10 MHz Bit Rate for 6.5536 MHz

Note: For Clock 5 and higher bit rates, the bit rate shown is the peak rate. The

data is burst out in pairs of bytes, and the overall average data rate is limited to

approximately 40 kbps and 25 kbps for 10 MHz and 6.5536 MHz input clocks,

respectively.
