Variable Clock Enable (Master Only)
0 = The serial clock output frequency is fixed and decided only by the value of
DIVIDER.
1 = The serial clock output frequency is variable. The output frequency is
decided by the value of VARCLK, DIVIDER, and DIVIDER2.
Note that when enable this VARCLK_EN bit, the setting of TX_BIT_LEN must
be programmed as 0x10 (16 bits mode)
Reserved
Reorder Mode Select
00 = Disable both Byte Reorder and byte suspend functions.
01 = Enable Byte Reorder function and insert a byte suspend interval (2~17
serial clock cycles) among each byte. The setting of TX_BIT_LEN must be
