selection of bits in the PSBANK register, as described in SFR Definition 9.1. All other devices with 64 kB or
less program memory can be used as non-banked devices.
The IFBANK bits select which of the upper banks are used for code execution, while the COBANK bits
select the bank to be used for direct writes and reads of the flash memory.
The address 0x1FFFF (C8051F960/1/2/3), 0xFFFF (C8051F964/5), 0x07FFF (C8051F966/7), or 0x3FFF
(C8051F9608/9) serves as the security lock byte for the device. Any addresses above the lock byte are
reserved.
