R5C841 PCI-CardBus/IEEE 1394/SD Card/Memory Stick/xD/ExpressCard Data Sheet
12345 2004 REV.1.10 4-8
4.10 Reset Event
Anytime GBRST# is asserted, all R5C841 internal state machines are reset and all registers are
set to their default values (provided that each signals has followed the reset sequence below).
PCIRST# is asserted, all registers are set to their default value except the following. The default
values of each register are described in each register description.
1. These registers are initialized only by GBRST#, not by PCIRST#. (PCI RESET Resistant register).
