5. CONFIGA register (offset 244) (R/W only in configuration mode)
0
7
Bit [0]- Indicates if interrupts are pulsed or level (Read only)
0: pulse
1: level
Bit [1:3 ]- Pword size (R/W)
001: Pword size = 1 byte
010: Pword size = 4 byte
000 and 011 ~ 111: reserved
Bit [4]- reserved
Bit [5]- nByteInTransceiver (Read only)
0: When transmiting (at host recovery), there is one byte in the transceiver waiting to be
transmitted that does not affect the FIFO full bit.
Bit [6:7]- Snapshot of the Pword
This field is not used for Pword size of 1 byte.
For host recovery situations these bits indicate what fraction of a Pword was not transmitted
so that software can re-transmit the unsent bytes. If the Pword size is 4 bytes the value of
these two bits is a snapshot of the last Pword being transmitted in mode 011 event 35 when
the FIFO was reset (port was transitioned from mode 011 to mode 000 or 001)
00- the Pword at the head of the FIFO contained a complete Pword
01- the Pword at the head of the FIFO contained only 1 valid bytes.
10- the Pword at the head of the FIFO containeed 2 valid bytes.
11- the Pword at the head of the FIFO contained 3 valid bytes.
6. Reverse address register (offset 245) (Read only)
0
7
Bit [0:1]- Reserved
Bit [2]- Tag_all
1: To indicate the unread bytes of the FIFO storing the reverse data/ command that has
at least one address bytes.
0: There is no address byte in the FIFO
Bit [3:6]- Tag0, Tag1, Tag2, Tag3
to check if there is one byte of the following read Pword = 4 bytes is the reverse address.
Tag0, Tag1, Tag2 and Tag3 are individually for the byte0, byte1, byte2 and byte3 of the
Pword
Bit [7]- Tag
to check if the byte of the following read Pword (1 byte) is the reverse address.
