address of the FLASH memory location to be addressed. When accessing data using LBP, the contents of
LAP2:LAP0 will increment after the read or write is complete.
Accessing LBP does the same thing as accessing LWP. The MMU register ordering of LWP followed by
LBP, allow the user to access data by words using the LDHX or STHX instructions with the address of the
LWP register.
4.4.3.5
This register is one of three data registers that the user can use to access any FLASH memory location in
the extended address map. When LB is accessed the contents of LAP2:LAP0 make up the extended
address of the FLASH memory location to be addressed.
4.4.3.6
The user can increase or decrease the contents of LAP2:LAP0 by writing a 2s complement value to
LAPAB. The value written will be added to the current contents of LAP2:LAP0.

Reads of this register will first return the data value pointed to by the linear address pointer, LAP2:LAP0 and then
will increment LAP2:LAP0. Writes to this register will first write the data value to the memory location specified
by the linear address pointer and then will increment LAP2:LAP0. Writes to this register are most commonly used
when writing to the FLASH block(s) during programming.
