Additional control of the MCM20014 can be had using
the Reset Control Register;
Reset Control Register; Ta-
ble 15
. Setting the
clt
bit of this register will tristate the
sync signals SOF, VLCK, and HCLK.
Setting the
ssr
bit of this register will reset all the non-
user programmable registers to a known reset state.
This is useful in situations when control of the
MCM20014 has been lost due to system interrupts and
the device needs only to be restarted using the earlier
user programmed values.
Setting the
sit
bit allows the user to completely reset the
MCM20014 to the default state via the serial control in-
terface.
For both reset bits,
ssr
and
sit
, the user must return
those bits to 0 to enable continued operation.
5.2 Gain Caliberation Block
The
DPGA Global Gain Register; Table 16
, allows the
user to set a global gain via a 6 bit register this is applied
universally to all the pixel outputs. This enables the user
to account for varying light conditions using a gain
range of 1x to 8x in steps of 0.12x. The default value for
this register results in unity gain.
