Errata No. 1
Problem: High asserted CS_N in SPI mode does not work.
Description:
(strapped to logic 1 at the rising edge of reset), the IA82527 will not read and write to register
0x02 CPU interface register. This will prevent proper configuration and operation of the chip.
Workaround:
configuration.

Summary
Detail
High asserted CS_N in SPI mode does
not work.
False message box interrupts are
generated on Msg Box 1 when RXIE is
set.
Message Box 15 receive interrupt enable
does not work.
The CPU writes to Msg Box 15 RAM
cannot be read back if MsgVal is set.
TXOK and RXOK bits in the Status
Register are cleared by the IA82527
Setting the IntPnd bit to 1 from CPU
interface will not cause Interrupt.
In SPI mode, if signal AD2/CSAS is configured for active high chip select
The workaround to using SPI interface mode is to use the low-active chip select
