11.8 PCM output function

The device provides the option for a PCM output function. The PCM output is enabled

if the ARM_CFG bits in the CHx_CF-G_U4 registers are configured for PCM output.

Selecting the PCM output enables the following functions:

• The non-interpolated sensor data output as defined in the DATATYPE0 bits in the

Chx_CFG_U3 register is saturated to 10-bits as shown in Section 11.6.4.9 and

converted to an unsigned value.

• The 10-bit sensor value is input into a summer clocked at 10 MHz.

• The carry from the summer circuit is output to the PCM pin.

A block diagram of the PCM output is shown in Figure 55.
