ITF1 SDA Input
This bit indicates the current value on the SDA1 pin.
ITF1 SCL Input
This bit indicates the current value on the SCL1 pin.
ITF1 SDA Output
When the CTL1 bit is low, this bit will be the value output
on the SDA1 pin.
ITF1 SCL Output
When the CTL1 bit is low, this bit will be the value output
on the SCL1 pin.
ITF1 Control
When this bit is high, the microcontroller does not have
control over the TWS interface #1 SCL and SCA output
lines. When low, the values for SCLO1 and SDAO1 will
be output on the TWS interface #1 bus.
