These bits should be cleared by the user.
The CLEN value should be programmed with the total number of bits in the character mi-
nus one. The total number of bits in the character is calculated as the sum of: 1 (start bit
always present) + number of data bits (5–14) + number of parity bits (0 or 1) + number of
stop bits (1 or 2).
Example: For 8 data bits, no parity, and 1 stop bit, the total number of bits in the character
is 1 + 8 + 0 + 1 = 10. Thus, CLEN should be programmed to 9.
The number of data bits in the character may range from 5 to 14 bits. If the data bit length
is less than 8 bits, the MSBs of each byte in memory are not used on transmit and are
written with zeros on receive. If the data bit length is more than 8 bits, the MSBs of each
16-bit word in memory are not used on transmit and are written with zeros on receive.
0 = One stop bit
1 = Two stop bits
0 = No parity
1 = Parity is enabled for the transmitter and receiver as determined by the PM bit.
0 = Odd parity
1 = Even parity
00 = GCI or SCIT support
01 = Reserved
10 = UART (must be selected for SMC UART operation)
11 = Totally transparent operation
The total number of bits in the character must never exceed 16.
Thus, if a 14-bit data length is chosen, SL must be set to one
stop bit, and parity should not be enabled. If a 13-bit data length
is chosen and parity is enabled, SL must be set to one stop bit.
The values 0 to 3 should not be written to CLEN, or erratic be-
havior may result.
