UART2 Special Mode Register 4
Bit 0 of UART2 special mode register 4 (address 0374
) are used to start condition generate bit. When
16
the SCL, SDA output select bit (bit 3 of U2SMR4 register) is “1” and this bit is “1”, then the start condition
is generated.
Bit 1 of UART2 special mode register 4 are used to restart condition generate bit.
When the SCL, SDA output select bit (bit 3 of U2SMR4 register) is “1” and this bit is “1“, then the restart
condition is generated.
Bit 2 of UART2 special mode register 4 are used to stop condition generate bit.
When the SCL, SDA output select bit (bit 3 of U2SMR4 register) is “1” and this bit is “1”, then the stop
condition is generated.
Bit 3 of UART2 special mode register 4 are used to SCL, SDA output select bit.
Functions changed by these bits are shown in table 1.15.17 and figure 1.15.31.
Bit 4 of UART2 special mode register 4 are used to ACK data bit.
When the SCL, SDA output select bit (bit 3 of U2SMR4 register) is “0” and the ACK data output enable bit
(bit 5 of U2SMR4 register) is “1”, then the content of ACK data bit is output to SDA pin.
Bit 5 of UART2 special mode register 4 are used to ACK data output enable bit.
When the SCL, SDA output select bit (bit 3 of U2SMR4 register) is “0” and this bit is “1”, then the content
of ACK data bit is output to SDA pin.
Bit 6 of UART2 special mode register 4 are used to SCL output stop bit.
When this bit is “1”, SCL output is stopped at stop condition detection. (Hi-impedance status).
Bit 7 of UART2 special mode register 4 are used to SCL wait output bit.
When this bit is “1”, SCL output is fixed to "L" at falling edge of 10th bit of clock. When this bit is “0”, SCL
output fixed to “L” is released.
