TMEN

Write a “0” to bit 7 of address 0Dh, the CPU will send a low pulse to TRST and reset the 8-bit counter.

Then read bit 7 of 0DH to get “1”.

TMEN=1, the 8-bit counter will be enabled. TMEN=0, the 8-bit counter will stop.

INS [2:0] selects timer interrupt source. The selection codes are as follows, 000: TMOUT [0], 001 TMOUT

[1], 010: TMOUT [2], 011: TMOUT [3], 100: TMOUT [4], 101: TMOUT [5], 110: TMOUT [6], 111: TMOUT

[7].

TMOUT [7:0] is the output of the 8-bit counter. It is read-only.
