Description:
...μPD75108A is a 4-bit single-chip CMOS microcomputer having a data processing capability comparable tothat of an 8-bit microcomputer. Operating at high speeds, the microcomputer allows data to be manipulatedin units of 1, 4, or 8 bits. In addition, various bit manipulation instructions are provided to reinforce I/Omanipulation capability. Equipped with I/Os for interfacing with peripheral circuits operating on a different... ...such small equipments as cameras and VCRs.Detailed functions are described in the following user’s manual.
