CSG 65CE02
The 65CE02 (a derivative of 6502/65C02) is a CPU core developed by Commodore Semiconductor Group (formerly known as Commodore MOS) that has been used in the CSG 4510 micro controller (that combined a CPU and several I/O components) in the Commodore C64DX/C65.
The bit operation capability of the 6502's and the 65C02 were poor which impeded bit-oriented compression or decompression algorithms like Huffman coding and so the 65EC02 and the 65SC02 got new bit operations.[1] Other new instruction features were new page indirect addressing using the Z register, 16-bit Read-modify-write, Relative jump, Stack pointer relative addressing, other new addressing modes, add. mode, and instruction combinations.[1]
A product that used the 65CE02 was the Commodore A2232 serial port card for the Amiga computer.[2] The A2232 clocks the 65EC02 at 3.58 MHz and provides 7x RS-232C serial ports. Each port can be driven independently at 50 - 19 200 bit/s. There is however a driver available on Aminet that allows 2 of the serial ports to be driven at 115 200 bit/s.[3]
