Revision Description
5930 ■ Added "Non-Blocking Read Cycle", "Normal Read Cycle", and "Write Cycle" sections to EPI chapter.
■ Corrected values for MAXADC0SPD and MAXADC1SPD bits in DC1, RCGC0, SCGC0, and DCGC0
registers.
■ Corrected figure "TI Synchronous Serial Frame Format (Single Transfer)".
■ Added description for Ethernet PHY power-saving modes.
■ Made a number of corrections to the Electrical Characteristics chapter:
– Deleted V_BAT and V_REFA parameters from and added footnotes to Recommended DC Operating
Conditions table.
– Deleted Nominal and Maximum Current Specifications section.
– Modified EPI SDRAM Characteristics table:
• Changed t_EPIR to t_SDRAMR and deleted values for 2-mA and 4-mA drive.

Timing, SDRAM Precharge Command Timing and SDRAM CAS Latency Timing figures and
replaced with SDRAM Read Timing and SDRAM Write Timing figures.
– Modified Host-Bus 8/16 Mode Write Timing figure.
– Modified General-Purpose Mode Read and Write Timing figure.
– Modified values for t_DV and t_DI parameters, and deleted t_OD parameter from EPI General-Purpose
Interface Characteristics figure.
– Major changes to ADC Characteristics tables, including adding additonal tables and diagram.
■ Added missing ROM_I2SIntStatus function to ROM DriverLib Functions appendix.
