QADC64E Enhanced Mode Operation
indicating that the module is locked in legacy mode. In order to change the value of the FLIP bit, the
operating mode must first be unlocked by setting the LOCK bit. Only then can the FLIP bit be changed.
Finally, the LOCK bit must be cleared again to protect the state of the FLIP bit from future writes.
14.3.1.4
The QADC64E memory map is divided into two segments: supervisor-only data space and assignable data
space. Access to supervisor-only data space is permitted only when the software is operating in supervisor
access mode. Assignable data space can be either restricted to supervisor-only access or unrestricted to
both supervisor and user data space accesses. The SUPV bit in the QADCMCR designates the assignable
space as supervisor or unrestricted.
The following information applies to accesses to address space located within the module’s 16-bit
boundaries and where the response is a bus error. See
14-10
1. Write LOCK = 1 to unlock operating mode bit.
2. Modify the value of FLIP as required.
3. Write LOCK = 0 and new FLIP bit value to preserve the value of FLIP bit
— FLIP = 0 legacy mode enabled
— FLIP = 1 enhanced mode enabled
Example 1: switching from legacy mode to enhanced mode
— QADCMCR = 0x280; LOCK =1, SUPV = 1
— QADCMCR = 0x380; LOCK =1, write FLIP = 1, SUPV = 1
— QADCMCR = 0x180; LOCK = 0, FLIP = 1, SUPV = 1
Subsequent writes to the FLIP bit will have no effect while LOCK = 0.
Example 2: switching from enhanced mode to legacy mode
— QADCMCR = 0x280 or 0x380; LOCK = 1, SUPV =1 (Can write FLIP = x since value will not
— QADCMCR = 0x280; LOCK = 1, FLIP = 0, SUPV = 1
— QADCMCR = 0x080; LOCK = 0, FLIP = 0, SUPV =1
Attempts to read a supervisor-only data space when not in the supervisor access mode and SUPV
= 1, causes the bus master to assert a bus error condition. No data is returned. If SUPV = 0, the
QADC64E asserts a bus error condition and no data is returned.
Attempts to write to supervisor-only data space when not in the supervisor access mode and SUPV
= 1, causes the bus master to assert a bus error condition. No data is written. If SUPV = 0, the
QADC64E asserts a bus error condition and the register is not written.
Attempts to read unimplemented data space in the unrestricted access mode and
SUPV = 1, causes the bus master to assert a bus error condition and no data is returned. In all other
attempts to read unimplemented data space, the QADC64E causes a bus error condition and no data
is returned.
Attempts to write unimplemented data space in the unrestricted access mode and
SUPV= 1, causes the bus master to assert a bus error condition and no data is written. In all other
