93hex =

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.)

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) = 2.786(4 bits), 2.229· (5 bits), 1.857 (6 bits) and 0.700 (Full bits).
