BIT [7:5] - Unused
BIT 4- Telecom Bus Interface - Detection of Parity Error Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the Receive STS-1/STS-3 Telecom Bus Interface has
detected a parity error within the incoming STS-1/STS-3 data-stream since the last read of this register, as described
below.
`
0 - Indicates that the Receive STS-1/STS-3 Telecom Bus Interface has NOT detected a parity error since the last read
of this register.
`
1 - Indicates that the Receive STS-1/STS-3 Telecom Bus Interface has detected a parity error (and has generated
the Detection of Parity Error interrupt) since the last read of this register.
N
OTE
:
This register bit-field is only active if the XRT86SH328 has been configured to exchange STS-1/STS-3 data via
the Telecom Bus Interface.
BIT [3:1] - Unused
BIT 0 - Telecom Bus Interface - Detection of Parity Error Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Receive STS-1/STS-3 Telecom Bus Interface -
Detection of Parity Error interrupt. If this interrupt is enabled, then the Receive STS-1/STS-3 Telecom Bus Interface will
generate this interrupt anytime it detects a parity error within the incoming STS-1/STS-3 data-stream.
`
0 - Disables the Receive STS-1/STS-3 Telecom Bus Interface - Detection of Parity Error interrupt.
`
1 - Enables the Receive STS-1/STS-3 Telecom Bus Interface - Detection of Parity Error interrupt.
Bits [7:0] -
General Purpose Input/Output Pin # 7 thru 0
The function of this READ/WRITE bit-field depends upon whether the GPIO_[7:0] pins are configured to be an input or
an output pin.
If GPIO_[7:0] is configured to be an input pin:
These register bits operates as a READ-ONLY bit-fields that reflects the state of the GPIO_[7:0] input pins.
If the GPIO_[7:0] input pins are pulled to a logic HIGH, then this register bit will be set to 1. Conversely, if the GPIO_7
input pin is pulled to a logic LOW, then this register bit will be set to 0.
If GPIO_[7:0] is configured to be an output pin
Tthe user can control the logic level of GPIO_[7:0] by writing the appropriate value into these bit-fields.
`
0 - Causes the GPIO_[7:0] output pins to be driven LOW.
`
1 - Causes the GPIO_[7:0] output pins to be driven HIGH.
