/**********************************************************************

|

Motorola 6821 PIA interface and emulation
|
||||
|
||||
Notes:
|
||||
* pia_get_port_b_z_mask() gives the caller the bitmask
|
||||
that show which bits are high-impendance when
|
||||
reading port B, thus neither 0 or 1.
|
||||
pia_get_output_cb2_z() returns the same
|
||||
information for the CB2 pin
|
||||
* pia_set_port_a_z_mask allows the input callback to
|
||||
indicate which port A bits are disconnected.
|
||||
For these bit, the read operation will return the
|
||||
output buffer's contents
|
||||
* the 'alt' interface functions are used when the A0 and A1
|
||||
address bits are swapped
|
||||
* all 'int' data or return values are Boolean
|
||||
