TEST CELL HOLDING
REGISTER
RO
0x00
Holds the “Unread” byte of the 16-bit Test Cell Error Accumulator, when that
register is read. The XRT72L74 will transfer the contents of the “Unread”
byte to this “Holding” register, anytime the Bidirectional Data Bus (of the
Microprocessor Interface) is configured to be 8-bits wide.
N
OTE
:
This register is only active if the XRT72L74 has been configured to
operate in the “ATM UNI” Mode.
