mask_gpio0

value_gpio1

7:4

always set to 0

The I²C address change is executed only if

(mask_gpio1 & GPIO1) << 1 + (mask_gpio0 & GPIO0) == value_gpio1

<< 1 + value_gpio0

where GPIO1 and GPIO0 is the current status on pin GPIO1 and pin

GPIO0. If this conditional programming is not used, set cmd_data0 to

0x00.

cmd_data1 = New I²C address

Bit

Set to ‘0’

7:1

New I²C address to be used

0x80..

0x93

Read 1 quarter of one histogram - copy histogram bits[4:2] to select

TDC0…TDC4, quarter bits[1:0] into 0x20..0x9f

NOTE: At the end of the transaction of read a quarter, the contents of

the registers from 0x20-0x9F will be automatically updated, and the

contents of registers REGISTER_CONTENTS and TID will be updated

NOTE: At the end of a TDC, the TDC number will also auto increment.

0xFF

Stop whatever you are doing as soon as possible and reenter the idle

state. The current state will not be interrupted and will require leaving

the current state processing to take effect. This command will stop

continuous measurement.
