Strap_lo

Strap Scan Value Hold Register (low)

0x21

Bit No.

Bit name

reserved

strap0

Operation

Default

0x00

strap15:

reserved, displays pin XYSNC_SAT_CFG

strap14:

I2C Device Address: A1, on HYSNC_A1

strap13:

I2C Device Address: A0, on VYSNC_PSDIAG_A0

strap12:

strap11 ... strap8:

reserved, not mapped to pins

strap7 ... strap0:

reserved, displays pins DATA[7:0]

Note 1:

Default start-up values of these registers are only valid until end of reset phase. Values might be overwritten by external pull-up

resistors during strap scan phase when reset is released.

Note 2:

Read access on this register does not initiate a strap scan phase. This register simply holds the last scanned value when reset

is released.
