(Note 20) The Segment Output Port function is assumed to be selected for the output pins – S1/P1/G1 to S9/P9/G9,
KS1/S53 to KS6/S58, KI1/S59 to KI5/S63, OSC_IN/S73.
During 1 chip mode, S66/TESTIN functions as TESTIN input.
During 2 chip mode(Master with Slave), CLKIO/S64 and SYNCIO/S65 function as CLK and SYNC outputs.
To illustrate further, the states of the S21 output pin is given in the table below.
