Table 6. Serial Sensor Parameters Register Bit Definitions
Three pins are used for the serial data interface. This interface converts the serial data into an (internal) parallel data bus
(Serial-Parallel Interface or SPI). The control lines are:

The initial state of the register is undefined. However, no state exists that destroys the device.

1 = power on sensor array ; 0 = power-down.
1 = power up output amplifier 4; 0 = power-down.
1 = power up output amplifier 3; 0 = power-down.
1 = power up output amplifier 2; 0 = power-down.
1 = power up output amplifier 1; 0 = power-down.
3-bit code for subsampling mode of X shift register:
000 = full resolution
001 = full resolution
010 = full resolution
3-bit code for subsampling mode of Y-shift registers:
000 = select 2, skip 2
001 = full resolution
010 = select 2, skip 2
Crossbar switch (output multiplexer) control bit initial value.
This initial value is clocked into the crossbar switch at a SYNC_YR rising edge pulse (when the array pointers
jump back to row 1).
The crossbar switch control bit selects the correspondence between multiplexer busses and output amplifiers.
Bus-to-output correspondence is according to the following table:
Bus
1 = Toggle crossbar switch control bit on every odd/even line. In order to let green pixels always use the same
output amplifier automatically, this bit must be set to 1. On every CLK_Y rising edge (when a new row is
selected), the crossbar switch control bit will toggle. Initial value (after SYNC_Y) is set by bit 12.
Not used.
1 = Power-up sensor array; 0 = Power-down.
