serial-port timing parameters (continued)
Unless otherwise indicated, the data-rate timings shown in Figure 23 and Figure 24 are valid for all serial-port
modes, including handshake. See serial-port timing parameter tables.
Timing diagrams shown in Figure 23 and Figure 24 show operations with the serial port global-control register
bits CLKXP = CLKRP = FSXP = FSRP = 0.
Timing diagrams shown in Figure 23 and Figure 24 depend upon the length of the serial-port word, n, where
n = 8, 16, 24, or 32 bits, respectively.
