Description
Description of the Global Control Register
The space control registers correspond to the CE memory spaces supported by
the EMIF. There are four CE space control registers that correspond to the four
external CE signals. The MTYPE field identifies the memory type for the corre
-
sponding CE space. If the MTYPE field selects an asynchronous type, the
remaining register fields specify the shaping of the address and control signals for
the access to that space. The MTYPE field should only be set during system ini
-
tialization. The exception is when CE1 is used for the ROM boot mode. In this
case the CE space can be configured to another asynchronous memory type.
6 Reserved A value written to this bit field location has no effect. The reserved bit location
is always read as 1.
5 EKEN Enable bit.
0 ECLKOUT is held low.
1 ECLKOUT is enabled to clock (default).
4 CLK1EN Enable bit
0 Not available on C6713. This bit must be programmed to zero for proper
operation.
3 CLK2EN Enable / disabled using SSCEN / SDCEN bits.
0 CLKOUT2 is held high.
1 CLKOUT2 is enabled to clock (default).
31..12 Reserved A value written to this bit field location has no effect. The bit field is always
read as 0.
