Table 30-15. SCI Format Control Register (SCIFORMAT) Field Descriptions
Bit Field Value Description
31-3 Reserved 0 Reads return 0. Writes have no effect.
2-0 CHAR Character length control bits. These bits set the SCI character length from 1 to 8 bits.
When data of fewer than eight bits in length is received, it is left-justified in SCIRD and
padded with trailing zeros.
Data read from the SCIRD should be shifted by software to make the received data right-
justified.
Data written to the SCITD should be right-justified but does not need to be padded with
leading zeros.
0 The character is 1 bit long.
1h The character is 2 bits long.
2h The character is 3 bits long.
3h The character is 4 bits long.
4h The character is 5 bits long.
5h The character is 6 bits long.
6h The character is 7 bits long.
7h The character is 8 bits long.
