Write Access: Timed Access Protected. Cannot be written by the application software if
set to 0000B by the serial loader. If a 0000B is written via the serial loader
and the security lock is set, the Partition will become 1111B. The same will
occur if write access is available and application software writes a 0000B. In
addition, these bits will be set to 1111B if security lock is cleared.
MCON.3: RG1
One of two bits that determine the range of program space. RG0 is located
in the RPCTL register.
Initialization: Unaffected by watchdog, external, or power–up resets. Set to 1 on a No V
LI
reset or a clearing of the security lock.
Read Access: Can be read at any time.
Write Access: Cannot be modified by the application software. Can only be written via the
Bootstrap Loader.
MCON.2: PES
Peripheral Enable Select. When this bit is set, the data space is controlled
by PE1–PE4. Peripherals are memory–mapped in 16K blocks, and are
accessed by MOVX instructions on the Byte–wide bus.
Initialization: Cleared by all resets.
Read Access: Can be read at any time.
Write Access: Can be written at any time.
MCON.1: PM
Partition Mode. When PM=0, a partitionable, continuous memory map is
invoked. When PM=1, one of four fixed allocations is used.
Initialization: Unaffected by watchdog, external, or power–up resets. Cleared on a No V
LI
reset.
Read Access: Can be read at any time.
Write Access: Cannot be modified by the application software. Can only be modified via
the Boostrap Loader.
MCON.0: SL
“Security Lock”: Indicates that the security lock is set when SL=1.
Initialization: Cleared to a 0 on a no V
LI
power on reset.
Read Access: Read normally any time.
Write Access: Can only be modified by the Lock and Unlock commands of the Bootstrap
loader. This bit cannot be modified by the application software or by the
Bootstrap loader Write command.
