The primary difference between Port A and the Port B is in the operation of the output buffers which drive these pins. The Port B output buffers are push-pull devices which are capable of sourcing 3 ma at l.5V. This allows these pins to directFy drive transistor switches. To assure that the microprocessor willd proper data on a "Read Port B" opefation, logic Fn the R6532 allows the microprocessor to read the Output Register instead of reading the peripheral pin as on Port A.
