94 / 147 page  Electrical Specifications 94 June 2004 SPRS257 tw(RSL) th(XPLLDIS) th(XMP/MC) tOSCST VDDIO, VDDAn, VDDAIO (3.3 V) XCLKIN X1 XRS XF/XPLLDIS XMP/MC VDD, VDD1 (1.8 V (or 1.9 V)) I/O Pins XPLLDIS Sampling Address/Data/ Control XCLKOUT (Don’t Care) (Don’t Care) GPIOF14/XF (User-Code Dependent) XCLKIN/8 (See Note A) (Don’t Care) Input Configuration (State Depends on Internal PU/PD) User-Code Dependent Address/Data/Control Valid Execution Begins From External Boot Address 0x3FFFC0 User-Code Dependent 2.5 V 0.3 V td(EX) NOTES: A. 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. B. The state of the GPIO pins is undefined (i.e., 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.. See Note B tsu(XPLLDIS) Figure 6−7. Power-on Reset in Microprocessor Mode (XMP/MC = 1) |
