SBUSY2 output SSTB2 output function select bit (bit 4 at address 034416)= “0” , “1”
SOUT2 Output
Either output active or high-impedance can be selected as a SOUT2 pin state at serial non-transfer by the
SOUT2 pin control bit (bit 6 of address 034416).
However, when the external synchronous clock is selected, perform the following setup to put the SOUT2
pin into a high-impedance state.
When the SCLK2i ( i = 1, 2) input is “H” after completion of transfer, set the SOUT2 pin control bit to “1”. When
the SCLK2i ( i = 1, 2) input goes to “L” after the start of the next serial transfer, the SOUT2 pin control bit is
automatically reset to “0” and put into an output active state.
