Bits 15:0 TXENm: Transmit output m function enable

0: The alternate function for Transmit output m is disabled and the corresponding pin becomes a

general-purpose IO (GPIO) or can be used by other alternate functions.

1: The alternate function for Transmit output m is enabled

Note: When PXSEN = 0, all transmit alternate functions are disabled.

Note: These bits can be modified only when CIPF = 0.

Note: All transmitters can be individually enabled to operate simultaneously.

MAX[15:8]

76543210

MAX[7:0]

Bits 15:10 Reserved

Bits 7:0 MAX[15:0]: 16-bit value indicating the maximum allowed value for the conversion data. When the

conversion data of a receiver channel reaches this value, the conversion stops. The conversion data

(PXS_RXnCNTR) is 0x0000 for those channels which did not reach the threshold voltage (VTHR) before

reaching the maximum count and their corresponding data-valid bit (VALIDn) is ‘0’ in PXS_RXSR.

Note: These registers can be modified only when CIPF = 0.
