Preliminary Technical Data
ADuC702x Series
FLASH/EE CONTROL INTERFACE
Rev. PrB | Page 33 of 80
Serial, parallel and JTAG programming use the Flash/EE
Control Interface, which includes seven MMRs:
-
FEESTA:
read only register, reflects the status of the Flash
Control Interface
-
FEEMOD:
sets the operating mode of the Flash Control
Interface
-
FEECON:
8-bit
command register. The commands are
described Table 14
-
FEEDAT:
16-bit data register.
-
FEEADR:
16-bit address register.
-
FEESIGN:
24-bit code signature
-
FEEPRO:
protection following subsequent reset MMR.
Requires software key. See description Table
15
-
FEEHIDE:
Immediate Protection MMR. Does not require
any software keys. See description Table 15

Reserved
Flash interrupt status bit
Set
automatically when an interrupt occurs, i.e. when a command is complete and the Flash/EE interrupt enable bit in the
FEEMOD register is set
Cleared
when reading FEESTA register
Flash/EE controller busy
Set
automatically when the controller is busy
Cleared
automatically when the controller is not busy
Command fail
Set
automatically when a command completes unsuccessfully
Cleared
automatically when reading FEESTA register
Command complete
Set
by MicroConverter when a command is complete
Cleared
automatically when reading FEESTA register

Description
Idle state
Load FEEDAT with the 16-bit data indexed by FEEADR
Write FEEDAT at the address pointed by FEEADR. This operation takes 20
μ
s.
Erase the page indexed by FEEADR and write FEEDAT at the location pointed by FEEADR. This operation
takes 20ms
Compare the contents of the location pointed by FEEADR to the data in FEEDAT. The result of the
comparison is returned in FEESTA bit 1
