Description
SDRAMφ Output Disable
Controls SDRAMφ.
0: SDRMφ output.
1: Can be used as PH1/CS5/RAS5.
When the SDRAMφ output is selected, the pin
functions as follows in each power-down mode.
Normal operation: SDRAMφ output
Sleep mode: SDRAMφ output
Software standby mode: Fixed at a high level
Hardware standby mode: High-impedance state
All module clock stop mode: SDRAMφ output
Reserved
This bit is always read as 0 and cannot be
modified.
Frequency Multiplication Factor Switching Mode
