Note. The time conversion factor varies depending on the compression bit mode.(M = 1,048,576 K= 1,024)
Residual time (sec) = Valid data residual (Mbits) × Time conversion value k
where the Time conversion value k (sec/Mbit) = 2.78(4 bits), 2.22 (5 bits), 1.85 (6 bits) and 0.74 (Full bits).
Extension I/O inputs 93
Input data entering (or output data) an extension port terminal is echoed to the microcontroller.
(That is, the input data entering an I/O port configured as an input port using the 81H command,
OR the output data from a pin configured as an output port using the 82H command.)
