Error Registers 3-13
3.7 Pchip Error Register (PERROR)
If any bits <11:0> are set, this register is frozen. Only bit <0> can be set after
that. All other values are held until all bits <11:0> are clear. When an error
occurs and one of the <11:0> bits set, the associated information is captured in bit
<63:16>. After the information is captured, the INV bit is cleared, but the
information is not valid and should not be used if INV is set.
