Schmitt trigger disable registers

The ADC_TDRH and ADC_TDRL registers are used to disable the Schmitt triggers available

in the AIN analog input pins. Disabling the Schmitt trigger lowers the power consumption in

the I/Os.

24.11

ADC registers

24.11.1

ADC data buffer register x high (ADC_DBxRH) (x=0..7 or 0..9 )

Address offset: 0x00 + 2 * channel number

Reset value: 0x00

Note:

Data buffer registers are not available for ADC2. The data buffer size and base address are

device dependent and are specified in the corresponding datasheet. Note that the data

buffer registers and the other ADC registers have different base addresses.

Bits 7:0 DBH[7:0] Data bits high

These bits are set/reset by hardware and are read only. When the ADC is in

buffered continuous or scan mode, they contain the high part of the converted

data. The data is in right-aligned or left-aligned format depending on the ALIGN

bit.

Left Data Alignment

These bits contain the eight MSB bits of the converted data.

Right Data Alignment

These bits contain the (eight ADC data width) MSB bits of the converted data.

Remaining bits are tied to zero.

See Figure 164.
