Table 30. TLIM Programming Registers
Table 31. Miscellaneous Configuration 2 Register
The TLIM Programming registers (R1Eh/R1Fh, Table 30)
are used to adjust the t
On a power-up or after a reset condition, this register is
set to a default value of 00h. When TLIM_[3:0] is set to
0000 the default t
any other value, the t
the decimal value of TLIM_[3:0].
These registers are reserved. Writing to these registers
is not recommended as they are internally connected. If
the software needs to do a large batch write command
using the address autoincrement function, write a code

The Miscellaneous Configuration 2 register (Table 31) is
used for several functions that do not cleanly fit within
one of the other configuration categories. On a power-up
or after a reset condition, this register is set to a default
value of 00h. When LSC_EN is set to 1, the load stabil-
ity safety check is enabled and the detection phase is
more immune to load variation. When VEE_R_ are set to
