Reference Information
Specific effects and operations are shown as follows by setting the bits of this register.
MOEXEUP bit: MOEX Width Setup
How to set up the MOEX width depends on the MOEXEUP bit setup.
0 1 2 3 4 5 6 7
MOEX
MCSX
RACC
RACC - RADC
RADC
In case of MOEXEUP = 0
MCLK
MOEX width is determined with (RACC-RADC).
0 1 2 3 4 5 6 7
MOEX
MCSX
RACC
FRADC
In case of MOEXEUP = 1
MCLK
RADC
MOEX width is determined with FRADC.
The following is the summary of MOEX width setups with page read setups and MOEXEUP setups.
MOEX width
=> RACC-RADC
Note:
Setup with RACC > RADC
is required.
MOEX width
=> FRADC
Note:
Setup with RACC RADC + FRADC
is required.
MOEX width
=> Simultaneous assertion with MCSX
Note:
Setup with RADC=0 is required.
