Chapter 2: Product Specification
Global Interrupt Enable Register
The Global Interrupt Enable register is described in Table 2-11 .
Interrupt Status Register
The Interrupt Status register (ISR) is described in Table 2-12 and captures the error and
status information for the core.
1 Stream Line buffer Full 0x0 R
Indicates the current status of line buffer
full condition
0
Soft reset/Core disable
in progress
0x0 R
Set to 1 by the core to indicate that
internal soft reset/core disable activities
are in progress

31–1 Reserved N/A N/A Reserved
0 Global Interrupt enable 0x0 R/W
Master enable for the device interrupt output to
the system
1: Enabled—the corresponding Interrupt Enable
register (IER) bits are used to generate interrupts
0: Disabled—Interrupt generation blocked
irrespective of IER bits

Description
31 Frame Received 0x0 R/W1C Asserted when the Frame End (FE) short
packet is received for the current frame
30 VCX Frame Error RO 0x0
Asserted when the VCX Frame error is
detected
30–23 Reserved N/A N/A N/A
22 Word Count (WC) corruption 0x0 R/W1C
Asserted when WC field of packet header
corrupted and core receives less bytes than
indicated in WC field. Such a case can occur
only where more than 2-bits of header are
corrupted which ECC algorithm cannot report
and the corruption is such that the ECC
algorithm reports a higher Word Count (WC)
value as part of ECC correction.
In such case core limits processing of the
packet on reduced number of bytes received
through PPI interface.
