8.1.12 R11 Register (Address = 0xB) [reset = 0x0000]

R11 is shown in Table 8-16.

Return to the Summary Table.

Table 8-14 R11 Register Field Descriptions
Bit Field Type Reset Description
15 Reserved R/W 0x0 Reserved. Only write '0' to this bit.
14 SEPARATE_OE_EN R/W 0x0

This bit enables the separate output enable functionality of the device. If this bit is a '1', then I2C_ADDR_LSB_SEL must be set to '0'. This field is stored in the EFUSE.

0h: Pin 1 is the output enable for OUTA, OUTB, OUTC, and OUTD.

1h: Pin 1 is the output enable for OUTA and OUTB, Pin 2 is the output enable for OUTC and OUTD.
13:0 Reserved R/W 0x0000 Reserved, do not write to this field.
