(1) TMS and TDI are not included due to internal pullups.
TRST is not included due to internal pulldown.
(2) Measured with average CPU activity:
50% of time: 8 instructions per cycle, 32-bit DMEM access per cycle
50% of time: 2 instructions per cycle, 16-bit DMEM access per cycle
(3) Measured with average peripheral activity:
50% of time: Timers at max rate, McBSPs at E1 rate, and DMA burst transfer between DMEM and SDRAM
50% of time: Timers at max rate, McBSPs at E1 rate, and DMA servicing McBSPs
(4) Measured with average I/O activity (30-pF load, SDCLK on):
25% of time: Reads from external SDRAM
25% of time: Writes to external SDRAM
50% of time: No activity
(5) This parameter is not tested.
