Description

Oversampling Register. Controls the degree of oversampling during each bit time.

Fields

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.
OSFRAC

Fractional part of the oversampling ratio, in units of 1/8th of an input clock period. (001 = 0.125, …, 111 = 0.875)
OSINT

Integer part of the oversampling ratio, minus 1. The reset values equate to the normal operating mode of 16 input clocks per bit time.
FDINT

In Smart Card mode, these bits act as a more-significant extension of the OSint field, allowing an oversampling ratio up to 2048 as required by ISO7816-3. In Smart Card mode, bits 14:4 should initially be set to 371, yielding an oversampling ratio of 372.
RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.
