These operations are valid when bits SC, IF1 and IF2 are all set to 1.

Note1:

Bits marked with an asterisk “(*)” are don’t-care.

Note2:

Bit names in parentheses “(

)” apply to the TC9256APG and TC9256AFG.

Note3:

Bits marked with (*1) cannot be set on the TC9256APG and TC9256AFG.

(4)

Bits f0 to f19.............................. The general-purpose counter results can be read in binary from bits f0

to f19 of the output register (D1H).

(5)

OVER and BUSY bits............... Detect the operating state of the general-purpose counter.

Note:

When using the general-purpose counter, confirm that the BUSY bit is “0” (counting is ended) and

the OVER bit is “0” (general-purpose counter data is normal) before referring to the contents of the

general-purpose counter result bits (f0 to f19).

(6)

START bit ................................. When the data is set to “1”, the general-purpose counter is reset; then

counting start.
