CHANNEL SETUP REGISTERS
8 Bits, Read/Write Registers, Address 0x28 to
Address 0x2F, Default Value 0x00
These registers are used to configure the selected channel, to
configure its input voltage range, and to set up the corresponding
channel status register (see Table 23 and Table 24).

7
BUFOFF
Buffer off. If reset to 0, then the internal buffer is enabled. Operation only with the internal buffer enabled is
recommended.

Stat OPT
Status option. When this bit is set to 1, the P0 and P1 bits in the channel status register reflect the state of the
P0 and P1 pins. When this bit is reset to 0, the RDY bit in the channel status register reflect the channel
corresponding to the RDY bit in the ADC status register.
3
Enable
Channel enable. Set this bit to 1 to enable the channel in the continuous conversion mode. A single
conversion takes place regardless of the value of this bit.

This is the channel input voltage range.
