DescriptionResetTypeNameBit/Field
Chip Select Baud Rate and Multiple Sub-Mode Configuration enable
This bit is only valid when the CSCFGEXT + CSCFG field is programmed
to 0x2 or 0x3, 0x5 or 0x6. This bit configures the baud rate settings for
CS0n, CS1n, CS2n, and CS3n.
This bit must also be set to allow different sub-mode configurations on
chip-selects. If this bit is clear, all chip-select sub-modes are based on
the MODE encoding defined in the EPI8HBCFG register.
If the CSBAUD bit is set in the EPIHBnCFG2 register and dual- or
quad-chip selects are enabled, then the individual chip selects can use
different clock frequencies, wait states and strobe polarity.
DescriptionValue
Same Baud Rate and Same Sub-Mode
All CSn use the baud rate for the external bus that is defined
by the COUNT0 field in the EPIBAUD register and the sub-mode
programmed in the MODE field of the EPIHB8CFG register.
0
Different Baud Rates
CS0n uses the baud rate for the external bus that is defined by
the COUNT0 field in the EPIBAUD register. CS1n uses the baud
rate defined by the COUNT1 field in the EPIBAUD register.
CS2n uses the baud rate for the external bus that is defined by
the COUNT0 field in the EPIBAUD2 register. CS3n uses the
baud rate defined by the COUNT1 field in the EPIBAUD2 register.
In addition, the sub-modes for each chip select are individually
programmed in their respective EPIHB8CFGn registers.
