Count registers of the timer/counters (TC1, TC2)

The 47C101/201 has two channels of 12-bit timer/

counters. The count register of the timer/counter is

assigned with a RAM addresses in unit of 4 bits, so

that the initial value is set and the contents are read by

using the RAM manipulation instruction.

The count registers are shared with the stack area

(locations 13 and 14) described earlier, so that the

stack is usable from location 13 when the timer/

counter 1 is not used. When none of timer/counter 1

and timer/counter 2 are used, the stack is usable from

location 14.

When both timer/counter 1 and timer/counter 2 are

used, the data memory locations at addresses 77H

and 7BH (37H and 3BH for the 47C101) can be used to

store the user-processed data.
