Description of Bits
•
UF0LG1-0 (bits 1 to 0)
UF0LG1-0 specify the character length of UARTF0.
UF0LG1 UF0LG0 Description
0 0 5-bit length (initial value)
0 1 6-bit length
1 0 7-bit length
1 1 8-bit length
•
UF0STP (bit 2)
UF0STP selects the stop bit count of the character transmitted by UARTF0.
UF0STP Description
0 1 stop bit (initial value)
1 1.5 stop bits (when character length = 5 bits)
2 stop bits (when character length = 6, 7, or 8 bits)
•
UF0PT2-0 (bits 5 to 3)
UF0PT2-0 select the parity bit of UARTF0.
UF0PT2 UF0PT1 UF0PT0 Description
* * 0 No parity bit (initial value)
0 0 1 Odd parity
0 1 1 Even parity
1 0 1 Parity bit fixed to "1"
1 1 1 Parity bit fixed to "0"
