Modifications:
• IEEE standard 802.3 compliance added to Section 11.13. Covers Ethernet dynamic
characteristics of ENET_MDIO and ENET_MDC signals.
• Parameter C
I
corrected for high-drive pins (changed from 2 pF to 5.2 pF). See
Table 10.
• Table 18 “Dynamic characteristic: I/O pins
[1]
” added.
• IRC accuracy changed from 1 % to 1.5 % over the full temperature range. See Table
16 “Dynamic characteristic: IRC oscillator”.
