Description
INTA Output
Controls the INTA output by software. This bit is valid
only when the PCIC operates in normal mode.
0: The INTA pin is in the high-impedance state (driven
1: Asserts INTA (output at low level)
PCIRST Output
Controls the PCIRST pin state by setting this bit to 1.
The PCIRST pin is output at low level at a power-on
reset.
0: Negates PCIRST (output at high level)
1: Asserts PCIRST (output at low level)
PCIC Internal Register Initialization Control
This bit should be set to 1 after the PCIC internal
registers are initialized. Setting this bit enables
accesses from the PCI bus. During initialization in
host mode, the bus mastership is not given to the
other devices on the PCI bus. In normal mode, the
PCIC returns RETRY without accepting the access
from the PCI bus when it is accessed from the PCI
bus.
0: Initialization being performed
1: Initialization completed
high by an on-chip pull-up resistor)
