DATA: Bi-directional three state data bus lines, connected to system data bus.
CLOCK 0: Clock input of Counter 0.
OUT 0: Output of Counter 0.
GATE 0: Gate input of Counter 0.
GROUND: Power supply connection.
OUT 1: Output of Counter 1.
GATE 1: Gate input of Counter 1.
CLOCK 1: Clock input of Counter 1.
GATE 2: Gate input of Counter 2.
OUT 2: Output of Counter 2.
CLOCK 2: Clock input of Counter 2.
ADDRESS: Select inputs for one of the three counters or Control Word Register for read/write
operations. Normally connected to the system address bus.
CHIP SELECT: A low on this input enables the HS-82C54RH to respond to RD and WR signals. RD
and WR are ignored otherwise.
READ: This input is low during CPU read operations.
WRITE: This input is low during CPU write operations.
VDD: The +5V power supply pin. A 0.1 F capacitor between pins 12 and 24 is recommended for
decoupling.
