P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
For the C6713/13B device, the PLL is bypassed immediately after the device comes out of reset. The PLL Controller can be programmed to
change the PLL mode in software. For more detailed information on the PLL Controller, see the
TMS320C6000 DSP Phase-Lock Loop (PLL)
Controller Peripheral Reference Guide
(literature number SPRU233).
§
The Boot and device configurations bits are latched asynchronously when RESET is transitioning high. The Boot and device configurations bits
consist of: HD[14, 8, 4:3].

P = 1/CPU clock frequency in ns.
Note that while internal reset is asserted low, the CPU clock (SYSCLK1) period is equal to the input clock (CLKIN) period multiplied by 8. For
example, if the CLKIN period is 20 ns, then the CPU clock (SYSCLK1) period is 20 ns x 8 = 160 ns. Therefore, P = SYSCLK1 = 160 ns while
internal reset is asserted.
#
The internal reset is stretched exactly 512 x CLKIN cycles if CLKIN is used (CLKMODE0 = 1). If the input clock (CLKIN) is not stable when RESET
is deasserted, the actual delay time may vary.
