DS5001/DS5002 SERIES MCON REGISTER Figure 4–8
PA3 PA2 PA1 PA0 RG1 PES PM –––
Bit Description:
MCON.7–4: PA3–0
Partition Address. When PM=0, this address specifies the boundary
between program and data memory in a continuous space.
Initialization: Unaffected by watchdog, external, or power–up resets. Set to 1111B on a
No V
LI
reset.
Read Access: Can be read normally at any time.
Write Access: Timed Access Protected. Also, cannot be written by the application soft-
ware 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 during
program load.
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.
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 reset. Cleared on a No V
LI
reset.
Read Access: Can be read at any time.
Write Access: Cannot be written by the application software. Can only be modified during
program load.
