Moreover, selection of the input mode cen also be carried out by directly rewriting
the data at address &FF45.
This conversion takes place by way of the lower 2 bits when the value to rewrite
this address is converted to a binary number.
Bit Description_______________________________
O Determines whether input from the keyboard is accepted or not.
O lnput from keyboard is accepted.
1 lnput from keyboard is not accepted.
1 Determines whether input from the bar code pen reader is accepted
or not.
O lnput from the bar code pen reader is not
accepted.
1 lnput from the bar code pen reader is accepted.
(Example) P0KE &FF45,2 2, as a binary number becomes 10. ln this case,
counting from the lower bit, bit 0 is 0 and bit 1 is 1.
