(c) Bus collision detection function (UART2)
interrupt request bit
This function reverses/inverts T
output (including the start bit, stop bit(s), and parity bit) is reversed. Set this function to “0” (not re-
versed/inverted) for normal use.
This function samples the output level of the T
edge of the transfer clock; if their values are different, then an interrupt request occurs. Figure 1.15.23
shows the example of detection timing of a bus collision (in UART mode).
