7.23 Channel Over Flow Status (address 2Bh) (Read Only)
For all bits in this register, a ‘1’ means the associated condition has occurred at least once since the register
was last read. A ‘0’ means the associated condition has NOT occurred since the last reading of the register.
Reading the register resets all bits to 0 if the Overflow Level/Edge interrupt type is set to “edge trigger”.
These channel overflow status bits are not effected by the interrupt mask bit, M_OVFL_INT. The overflow
condition of each channel can be polled instead of generating an interrupt as required.
7.23.1 ChXX_OVFL
Default = 0
Function:
When high, indicates that the magnitude of the current output sample on the associated channel has ex-
ceeded full scale and has been clipped to positive or negative full scale as appropriate.
7.24 GPIO Pin In/Out (address 2Ch)
7.24.1 GPIO In/Out Selection (GPIOX_I/O)
Default = 0
0 - General Purpose Input
1 - General Purpose Output
Function:
General Purpose Input
- The pin is configured as an input.
General Purpose Output
- The pin is configured as a general purpose output.
7.25 GPIO Pin Polarity/Type (address 2Dh)
7.25.1 GPIO Polarity/Type Selection (GPIOX_P/T)
Default = 1
Function:
General Purpose Input
- If the pin is configured as an input, this bit defines the input polarity (0 = Active
Low, 1 = Active High).
General Purpose Output
- If the pin is configured as a general purpose output, this bit defines the GPIO
output type (0 = CMOS, 1 = OPEN-DRAIN).
