Description
Not used.
upsel_value
This register defaults to reflecting the value present
on the UPSEL pins of the device at reset. At reset this
is used to set the mode of the microprocessor
interface. Following power-up, these pins have no
further effect on the microprocessor interface.
*In order that the device can be "booted" from an
EPROM and subsequently communicate with a
processor, this register is programmable in EPROM
mode. The value programmed in location 7F of the
EPROM will be the value loaded into this register.
**The default of this register is entirely dependent on
the value of the pins at reset.
