4.3
Characteristics: fully transparent
When programmed in the extended transparent mode via the
MDS1, MDS0, ADM = ‘111’), the SCC performs fully transparent data transmission and
reception without HDLC framing, i.e. without
• FLAG insertion and deletion
• CRC generation and checking
• bit stuffing.
This feature can be profitably used e.g. for:
• user specific protocol variations
• line state monitoring, or
• test purposes, in particular for monitoring or intentionally generating HDLC protocol
Character or octet boundary synchronization can be achieved by using clock mode 5 or
clock mode 1 with an external receive strobe input to pin CD.
Note: Data is transmitted and received with the least significant bit (LSB) first.

4.4.1
Character framing is achieved by start and stop bits. Each data character is preceded by
one Start bit and terminated by one or two stop bits. The character length is selectable
from 5 up to 8 bits. Optionally, a parity bit can be added which complements the number
of ones to an even or odd quantity (even/odd parity). The parity bit can also be
programmed to have a fixed value (Mark or Space). The character format configuration
is performed via appropriate bit fields in registers CCR3L/CCR3H.
