High-Performance 16-bit Non-PCI 10/100 Ethernet Controller with Variable Voltage I/O
Fixed various typos
Fixed various typos
Added power consumption values.
Updated with current consumption values for
various VDDVARIO values.
Added input capacitance and input leakage values.
Changed incorrect “GPT_CNT” reference to
“GPT_LOAD”: “On a reset, or when the
TIMER_EN bit changes from set ‘1’ to cleared ‘0,’
the GPT_LOAD field is initialized to FFFFh.”
Corrected MAC Address Loaded (bit 8) type from
“RO” to “R/WC”
Updated crystal specifications:
Drive Level: 300uW
ESR: 50 Ohms.
Note following I/O Buffer Characteristics table
modified:
Changed from: ".....the per-pin input leakage is 10
divided by the maximum input leakage current."
to: ".....the per-pin input leakage is the maximum
input leakage current divided by 10."
Diagram redone.
The word “Core” was added to the regulator block
title.
Changed VDD_CORE/VDD18CORE bulk
capacitor value from 10uF to 4.7uF.
