Table 5-3 Reset (XRS) Timing Requirements(1)

MIN NOM MAX UNIT
tw(RSL1) Pulse duration, stable XCLKIN to XRS high 8tc(CI) cycles
tw(RSL2) Pulse duration, XRS low Warm reset 8tc(CI) cycles
tw(WDRS) Pulse duration, reset pulse generated by watchdog 512tc(CI) cycles
td(EX) Delay time, address/data valid after XRS high 32tc(CI) cycles
tOSCST(2) Oscillator start-up time 1 10 ms
tsu(XPLLDIS) Setup time for XPLLDIS pin 16tc(CI) cycles
th(XPLLDIS) Hold time for XPLLDIS pin 16tc(CI) cycles
th(XMP/MC) Hold time for XMP/MC pin 16tc(CI) cycles
th(boot-mode) Hold time for boot-mode pins 2520tc(CI)(3) cycles
(1) If external oscillator/clock source are used, reset time has to be low at least for 1 ms after VDD reaches 1.5 V.
(2) Dependent on crystal/resonator and board design.
(3) The boot ROM reads the password locations. Therefore, this timing requirement includes the wakeup time for flash. See the TMS320x281x DSP Boot ROM Reference Guide and the TMS320x281x DSP System Control and Interrupts Reference Guide for further information.

B. Upon power up, SYSCLKOUT is XCLKIN/2 if the PLL is enabled. Since both the XTIMCLK and CLKMODE bits in the XINTCNF2 register come up with a reset state of 1, SYSCLKOUT is further divided by 4 before it appears at XCLKOUT. This explains why XCLKOUT = XCLKIN/8 during this phase.
C. After reset, the Boot ROM code executes instructions for 1260 SYSCLKOUT cycles (SYSCLKOUT = XCLKIN/2) and then samples BOOT Mode pins. Based on the status of the Boot Mode pin, the boot code branches to destination memory or boot code function in ROM. The BOOT Mode pins should be held high/low for at least 2520 XCLKIN cycles from boot ROM execution time for proper selection of Boot modes.
If Boot ROM code executes after power-on conditions (in debugger environment), the Boot code execution time is based on the current SYSCLKOUT speed. The SYSCLKOUT will be based on user environment and could be with or without PLL enabled.
D. The state of the GPIO pins is undefined (that is, they could be input or output) until the 1.8-V (or 1.9-V) supply reaches at least 1 V and 3.3-V supply reaches 2.5 V.
