UART2 Special Mode Register 2

Functions available in I
Bit 3 of the UART2 special mode register 2 (address 0376
this bit to “1” causes an arbitration loss to occur, and the SDA pin turns to high-impedance state at the
instant when the arbitration lost detecting flag is set to “1”.
Bit 1 of the UART2 special mode register 2 (address 0376
With this bit set to “1” at the time when the internal SCL is set to “H”, the internal SCL turns to “L” if the
falling edge is found in the SCL pin; and the baud rate generator reloads the set value, and start counting
within the “L” interval. When the internal SCL changes from “L” to “H” with the SCL pin set to “L”, stops
counting the baud rate generator, and starts counting it again when the SCL pin turns to “H”. Due to this
function, the UART2 transmission-reception clock becomes the logical product of the signal flowing
through the internal SCL and that flowing through the SCL pin. This function operates over the period
from the moment earlier by a half cycle than falling edge of the UART2 first clock to the rising edge of the
ninth bit. To use this function, choose the internal clock for the transfer clock.
Bit 2 of the UART2 special mode register 2 (0376
“1” causes the SCL pin to be fixed to “L” at the falling edge of the ninth bit of the clock. Setting this bit to
“0” frees the output fixed to “L”.
