CSPAR1 contains five 2-bit fields that determine the functions of corresponding chip-select pins.
CSPAR1[15:10] are not used. These bits always read zero; writes have no effect.
At reset, either the alternate function (01) or chip-select function (11) can be encoded. DATA pins are
driven to logic level one by a weak interval pull-up during reset. Encoding is for chip-select function un-
less a data line is held low during reset. Note that bus loading can overcome the weak pull-up and hold
pins low during reset. The following table shows the hierarchical selection method that determines the
reset functions of pins controlled by CSPAR1.
A pin programmed as a discrete output drives an external signal to the value specified in the port C
pin data register (PORTC), with the following exceptions:
1.
2.
No discrete output function is available on pins BR, BG, or BGACK.
ADDR23 provides E-clock output rather than a discrete output signal.
When a pin is programmed for discrete output or alternate function, internal chip-select logic still func-
tions and can be used to generate DSACK or AVEC internally on an address match.
Port size is determined when a pin is assigned as a chip select. When a pin is assigned to an 8-bit port,
the chip select is asserted at all addresses within the block range. If a pin is assigned to a 16-bit port,
the upper/lower byte field of the option register selects the byte with which the chip select is associated.
