Field Description
UCPC Bus Control Status Reg Displays the status of both TCC+ cards and of the LCD
Display Panel. Each TCC+ card displays this field from its
own point of view, where “this card” refers to itself and “the
other card” refers to the other TCC+ card slot.
Bits 2–0 display the status of the other TCC+ card:
– 0x00=No card.
– 0x03=The other card is the backup card.
– 0x05=The other card is the active card.
Bit 3 is set to 1 upon a state change for the other TCC+
card.
Bits 6–4 display the status of this TCC+ card:
– 0x00=No card.
– 0x03=This card is the backup card.
– 0x05=This card is the active card.
– 0x06=This card has assumed the active card role,
because the other card had been active but is now
unresponsive.
Bit 7 is set to 1 upon a state change for this TCC+ card.
Bits 13–8 are unused.
Bit 14 is set to 1 if the LCD Display Panel is present.
Bit 15 is set to 1 if the presence of the LCD Display Panel
has changed since the counters were last cleared.
