20 / 546 page Table 1. Revision History (continued) Description Revision Date ■ Added JTAG/SWD clarification (see “Communication with JTAG/SWD” on page 57). ■ Added clarification that the PLL operates at 400 MHz, but is divided by two prior to the application of the output divisor. ■ Added "GPIO Module DC Characteristics" table (see Table 20-4 on page 504). ■ Additional minor data sheet clarifications and corrections. 5367 April 2009 ■ Clarified Power-on reset and RST pin operation; added new diagrams. ■ Corrected the reset value of the Hibernation Data (HIBDATA) and Hibernation Control (HIBCTL) registers. ■ Clarified explanation of nonvolatile register programming in Internal Memory chapter. ■ Added explanation of reset value to FMPRE0/1/2/3, FMPPE0/1/2/3, USER_DBG, and USER_REG0/1 registers. ■ Added description for Ethernet PHY power-saving modes. ■ Corrected the reset values for bits 6 and 7 in the Ethernet MR24 register. ■ Changed buffer type for WAKE pin to TTL and HIB pin to OD. ■ In ADC characteristics table, changed Max value for GAIN parameter from ±1 to ±3 and added EIR (Internal voltage reference error) parameter. ■ Additional minor data sheet clarifications and corrections. 5902 July 2009 Corrected ordering numbers. 5920 July 2009 ■ Removed erroneous reference to the WRC bit in the Hibernation chapter. ■ Deleted reset value for 16-bit mode from GPTMTAILR, GPTMTAMATCHR, and GPTMTAR registers because the module resets in 32-bit mode. ■ Clarified CAN bit timing and corrected examples. ■ Made these changes to the Electrical Characteristics chapter: – Removed VSIH and VSIL parameters from Operating Conditions table. – Added table showing actual PLL frequency depending on input crystal. – Changed the name of the tHIB_REG_WRITE parameter to tHIB_REG_ACCESS. – Changed SSI set up and hold times to be expressed in system clocks, not ns. 6462 October 2009 April 04, 2010 20 Texas Instruments-Production Data Revision History |
