This status register indicates the number of packets transmitted and is active only if
continuous mode is in effect. The counter is reset if the following occurs:
Reset Controller bit, PCITER[RC], is asserted (normal way to restart continuous
mode)
Master Enable bit, PCITER[ME], becomes negated
Master enable can reset Packets_Done status without disturbing continuous mode
addressing. At any point in time, the total number of Bytes transmitted can be calculated
as:
(Packets_Done x Packet_Size) + Bytes_Done
assuming Packet_Size is the same for all restart sequences

Unused. Software should write zero to these bits.
This flag is set when any packet terminates normally. It is NOT set for abnormally terminated
packets.
Note: Flag does not require clearing, but does not clear until 1 is written, in which case 0 is
read back (i.e., negated). The following flag bits operate similarly.
This flag is set whenever a Slave bus transaction attempts to write to a Read-Only register.
This flag bit is set regardless of the Bus error Enable bit (BE). If software is polling this Byte
and wishes to disregard this error it must mask this bit out.
No register bit corruption occurs for this (or any other) bus error case.
This flag is set whenever a Slave bus transaction attempts to write to a Reserved register (an
entire 32-bit register, not just a Reserved bit or byte). This flag bit is set regardless of the Bus
error Enable bit (BE). If software is polling this Byte and wishes to disregard this error it must
mask this bit out.
