*1) All the listed data can be read and written except for ADJ/XSTP.
*2) The “–” mark indicates data which can be read only and set to “0” when read.
*3) The ADJ/XSTP bit of the control register2 is set to ADJ for write and XSTP for read operation. The XSTP bit is set to “0” by writing data into the con-
trol register2 for normal oscillation.
*4) When XSTP is set to “1”, the XSL, F6 to F0, CT2 to CT0, AALE, BALE, SL2, SL1, CLEN and TEST bits are reset to “0”.
*5) SL1 and SL2 apply to the RS5C372A. For the RS5C372B, these bits must be filled with “0”.
