CLKRP = CLKXP = FSRP = FSXP = 0. If the polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
P = 1/CPU clock frequency in ns. For example, when running parts at 200 MHz, use P = 5 ns.
§ The maximum bit rate for the C6205 devices is 100 Mbps or CPU/2 (the slower of the two). Care must be taken to ensure that the AC timings
specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 200 MHz
(P = 5 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP
communications applies when the serial port is a master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX,
CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP
communicates to is a slave.
The minimum CLKR/X pulse duration is either (P 1) or 4 ns, whichever is larger. For example, when running parts at 200 MHz (P = 5 ns), use
4 ns as the minimum CLKR/X pulse duration. When running parts at 100 MHz (P = 10 ns), use (P 1) = 9 ns as the minimum CLKR/X pulse
duration.
