CP (FE10
Note: It is the user's responsibility that the physical GPR address specified via CP
The CP register can be updated via any instruction which is capable of modifying an
SFR.
Note: Due to the internal instruction pipeline, a new CP value is not yet usable for GPR
The Switch Context instruction (SCXT) allows to save the content of register CP on the
stack and updating it with a new value in just one machine cycle.

register plus short GPR address must always be an internal RAM location. If this
condition is not met, unexpected results may occur.
• Do not set CP below the IRAM start address, ie. 00’FA00
(1/2/3 KB)
• Do not set CP above 00’FDFE
• Be careful using the upper GPRs with CP above 00’FDE0

Function
Modifiable portion of register CP
Specifies the (word) base address of the current register bank.
When writing a value to register CP with bits CP.11...CP.9 = ‘000’, bits
CP.11...CP.10 are set to ‘11’ by hardware, in all other cases all bits of bit
field “cp” receive the written value.
