The RAM portion is designed with 2K bit static cells organized as 256 x 8. The 14 bit programmable counter/ timer is the down counter. It provides either a square wave or terminal count pulse for the cpu system depending on timer mode. The I/O portion is consists of 2 programmable 8 bit I/O ports and 1 program~ mable 6 bit I/O port. The programmable I/O ports can be operated by BASIC MODE and STROBE MODE.
