AS3955 − Detailed Description
Direct Command Mode
Direct Command Mode is comprised of one command byte and
argument byte. The two msb’s of command code 11b indicate
Direct Command Mode. The following six bits define command
code, sent MSB first. Last two bits in argument byte indicate
success of the direct command. Value 01h of the argument byte
indicates that command was accepted, while 02h indicates it
was rejected due to internal access priorities. The argument
byte does not provide information on timing of the command
execution.

I²C Electrical Connection
The AS3955 has two built-in 3kΩ pull-up resistors on SDA and
SCL lines as shown on Figure 80 and used only in I²C mode. The
SPI pull-down bits in IO Configuration Register must be set 00h.
