Field Description
BUSREQ †
BUSREQ = 0; BUSREQ ouput is low.
BUSREQ = 1; BUSREQ output is high.
ARDY ARDY = 0: ARDY input is low.
ARDY = 1: ARDY input is high.
HOLD HOLD = 0: HOLD input is low.
HOLD = 1: HOLD input is high.
HOLDA HOLDA = 0: HOLDA output is low.
HOLDA = 1: HOLDA output is high.
NOHOLD External HOLD disable
NOHOLD = 0: hold enabled
NOHOLD = 1: hold disabled
SDCEN ‡
SDCLK enable
SDCEN = 0: SDCLK held high
SDCEN = 1: SDCLK enabled to clock
There is no SDCLK on the 'C6211/C6711. All external memories run
off the EMIF external clock, ECLKIN/ECLKOUT. SDCEN enables
CLKOUT2 on the 'C6202 if SDRAM is used in the system (specified
by the MTYPE field in in the CE space control register).
SSCEN ‡
SSCLK enable
SSCEN = 0: SSCLK held high
SSCEN = 1: SSCLK enabled to clock
There is no SSCLK on the 'C6211/C6711. All external memories run
off of the EMIF external clock, ECLKIN/ECLKOUT. SSCEN enables
CLKOUT2 on the 'C6202 if SBSRAM is used in the system
(specified by the MTYPE field in in the CE space control register).
CLK1EN CLKOUT1 enable
CLK1EN = 0: CLKOUT1 held high
CLK1EN = 1: CLKOUT1 enabled to clock
§
CLK2EN CLKOUT2 enable
CLK2EN = 0: CLKOUT2 held high
CLK2EN = 1: CLKOUT2 enabled to clock
CLKOUT2 is enabled/disabled using SSCEN/SDCEN on the 'C6202
