Address
Register,
PADR[15:0]. The contents of this
register are loaded from EE-
PROM after H_RESET or by an
EEPROM
read
(PRGAD, BCR19, bit 14). If the
EEPROM is not present, the con-
tents of this register are unde-
fined.

This register can also be loaded
from the initialization block after
the INIT bit in CSR0 has been set
or a direct register write has been
performed on this register.
Read/Write accessible only when
either the STOP or the SPND bit
is set. These bits are unaffected
by H_RESET, S_RESET, or
