10. Dynamic characteristics
[1]
Applies to external clock, crystal oscillator max 24 MHz.
[2]
= 333 ns (for Baudratemax = 1.5 Mbits/s)
= 1
s (for Baudrate
max = 460.8 kbits/s)
= 4
s (for Baudrate
max = 115.2 kbits/s)
[3]
When in both DMA mode 0 and FIFO enable mode, the write cycle delay should be larger than one x1, clock cycle.
