If the number of bits set by BRGC6 runs short, adjust the number of bits by setting the base clock of
UART6.
INTST6: Transmission completion interrupt request
Set TXE6 bit of ASIM6 register to 1 to
enable transmission.
Read BRGC6 register and save current
set value of BRGC6 register to general-
purpose register.
Set value to BRGC6 register to realize
desired SBF length.
Set character length of data to 8 bits
and parity to 0 or even using ASIM6
register.
X
Clear TXE6 and RXE6 bits of ASIM6
register to 0 (to disable transmission/
reception).
Set TXB6 register to "00H" and start
transmission.
