Asynchronous Memory Timing section:
Timing Requirements for Asynchronous Memory Cycles for EMIFA Module table:
Deleted “The AARDY signal is recognized in the cycle for which the setup and hold time is met.” from the AARDY signal
footnote
Added “The AARDY signal is
only
recognized two cycles before the end of the programmed strobe time and while AARDY is
low, the strobe time is extended cycle-by-cycle. When AARDY is recognized low, the end of the strobe time is two cycles
after AARDY is recognized high.” to the AARDY footnote
126
HOLD/HOLDA Timing section:
Timing Requirements for the HOLD/HOLDA Cycles for EMIFA Module table:
Changed parameter NO. 3
from
“toh(HOLDAL-HOLDL)”
to
“th(HOLDAL-HOLDL)”
128129
Reset Timing section:
Timing Requirements for Reset table:
Changed the MIN value of parameter No. 17, th(boot)
from
“4E or 4C” ns
to
“4P” ns
Added the associated “P note” footnote
Added parameter NO. 18, “td(PCLKRSTH) Delay time, PCLK active to RESET high” with a MIN value of “32N” ns
Changed parameter NO. 18 description
from
“td(PCLKRSTH) Delay time, PCLK active to RESET high”
to
“tsu(PCLK-RSTH),
Setup time, PCLK active before RESET high”
Added associated footnote to identify “N” and restraints
Switching Characteristics Over Recommended Operating Conditions During Reset table:
Updated footnote symbols
Figure 101, Reset Timing:
Updated figure to include the PCLK signal and parameter 18
Added “MAC_EN” to the “If AEA[22:19], LENDIAN, PCIEEAI, and HD5/AD5 pins ...” footnote
Added/Updated the “Boot and Device Configurations Inputs (during reset) include: ...” footnote
133
Host-Port Interface (HPI) Timing section:
Switching Characteristics Over Recommended Operating Conditions During Host-Port Interface Cycles table:
Added “mode, 2nd half-word” to parameter NO. 16 “td(HSTBL-HDV), Delay time, HSTROBE low to HD valid (HPI16 only)”
141142

Timing Requirements for McBSP table:
Added the MIN value of “or 6.67” ns to No. 2, tc(CKRX) parameter
Changed/updated the associated footnote
Switching Characteristics Over Recommended Operating Conditions for McBSP table:
Added the MIN value of “or 6.67” ns to No. 2, tc(CKRX) parameter
Changed/updated the associated footnote

Deleted parameter No. 4, “tt(MRCLK), Transition time, MRCLK”
Deleted associated reference points for rise and fall transitions footnote
Updated/changed Figure 161, MRCLK Timing (EMAC Receive)
149
Ethernet Media Access Controller (EMAC) Timing section:
Timing Requirements for MTCLK table:
Deleted parameter No. 4, “tt(MTCLK), Transition time, MTCLK”
Deleted associated reference points for rise and fall transitions footnote
Updated/changed Figure 162, MTCLK Timing (EMAC Transmit)
