|CSG 65CE02 registers|
The 65CE02 is an improved version of the 6502. It is fabricated using 2 µm CMOS technology, allowing for lower power operation compared to previous NMOS and HMOS versions of the 65xx family. It is housed in a 40-pin DIP that is pin compatible with the 6502.
Internally, the pipeline of the 65CE02 was redesigned to reduce the number of cycles required to execute an instruction. The 65CE02 can recover faster from engagement of the SYNC signal, which reduces the minimum instruction execution time from 2 cycles to 1 cycle. These improvements allow the 65CE02 to execute code up to 25% faster than previous 65xx models.
The 65CE02 uses a superset of the Rockwell 65SC02 instruction set. In addition to the enhancements and bug fixes included in the 65SC02, the 65CE02 includes new instructions for indirect jumps (allows the use of jump tables), 16-bit branches, bit shifting (ASR) and stack relative loads/stores. Several read-modify-write memory instructions (ASL/DEC/INC/PSH/ROR) were enhanced to support 16-bit values. Lastly, instructions supporting the new registers were added.
The 65CE02 was used in the Commodore A2232 serial port card for the Amiga computer. The 4510 was used in the unreleased Commodore 65 home computer  and the unreleased Commodore CDTV cost-reduced revision.
