XRLRCK[1:0], PSBCK[1:0], PSLRCK[1:0], XSBCK[1:0], and XSLRCK[1:0].
Setting range for each clock output pins when the TMCK is used as source
The polarity of RBCK, RLRCK, SBCK, and SLRCK can be reversed with RBCKP, RLRCKP, SBCKP, and SLRCKP.
CE.
The LC89057W-VF4A-E features two clock systems (R and S systems) in order to supply the various needed clocks
The clock output settings for the R and S systems are done with PRSEL[1:0], XRSEL[1:0], XRBCK[1:0],
Setting range for each clock output pin when the PLL is used as source
Setting range for each clock output pins when the XIN is used as source
Clock switching is processed from the rising edge of RLRCK output after the falling edge of microcontroller interface
