sent to the Addr:00 Output field. If the Sim_Trim bit at Address 10
is set to 1, the write affects the operation of the
with the new settings written by the user. The Sim_Trim bit is
set to 0 until the device is powered down, or until new settings
are written.
Write/Read Addr:01
Click Write/Read Addr:01 to perform a single write comprised
of the bit pattern set by the user in the OC_2Lev_OP field, the
Low_T_OP field, the OC_Blank_OP field, the td_OC field, the
Flyback_V field, the T_ramp_OP field, and the PWM_OSC
field. After the single write, a single read is performed, allowing
the user to verify that the sequence is sent. The result of this
read is sent to the Addr:01 Output field. If the Sim_Trim bit at
Address 10 is set to 1, the write affects the operation of the
ADuM4138 with the new settings written by the user. The
Sim_Trim bit is set to 0 until the device is powered down, or
until new settings are written.

Write/Read Addr:10
Click Write/Read Addr:10 to perform a single write comprised
of the bit pattern set by the user in the Prog Busy field and the
Sim Trim field. After the single write, a single read is performed,
allowing the user to verify that the sequence is sent. The result
of this read is sent to the Addr:10 Output field. If Sim_Trim is
set to 1, and then Prog_Busy is set to 1, values written to the
ADuM4138 using Write/Read Addr:00 and Write/Read Addr:01
are written to EEPROM and are loaded on the next power up.
These can be verified with an address read after a power up.
sclkFrequency
This field is used to change the operating frequency of the SPI
clocking. The field is set in hertz, and 200 kHz is the default and
maximum value.
