7.10 Timing and Switching Characteristics

Note

The Timing Requirements and Switching Characteristics values may change following the silicon

characterization result.

Note

The default SLEWRATE settings in each pad configuration register must be used to ensure timings,

unless specific instructions are given otherwise.

7.10.1 Timing Parameters and Information

The timing parameter symbols used in Timing and Switching Characteristics sections are created in accordance

with JEDEC Standard 100. To shorten the symbols, some pin names and other related terminologies have been

abbreviated in Table 7-3:
