4.3.1 Program Chip Select (CSPROG)
The program chip select (CSPROG) is active in the range of memory where the main program exists.
CSPROG is enabled out of reset in all modes. After reset in normal mode, the PCS stretch select bit is
set to provide one cycle of stretch so that slow memory devices can be used.
4.3.2 I/O Chip Select (CSIO)
The I/O chip select (CSIO) is programmable for a four Kbyte size located at addresses $1000 to $1FFF
or eight Kbyte size located at addresses $0000 to $1FFF. Polarity of the active state is programmable
for active high or active low. Clock stretching can be set from zero to three cycles.

Refer to GPCS1C (GPCS2C) —2K to 512K in nine steps, 0K = dis-
able, can also follow memory expansion window 1 or window 2
Refer to GPCS1A (GPCS2A)
Refer to CSCSTR —0, 1, 2, or 3 E clocks
G1DG2 in GPCS1C allows CSGP1 and CSGP2 to be connected to
an internal OR gate and driven out the CSGP2 pin.

G1DPC in GPCS1C allows CSGP1 and CSPROG to be connected to
an internal OR gate and driven out the CSPROG pin.
G2DPC in GPCS2C allows CSGP2 and CSPROG to be connected to
an internal OR gate and driven out the CSPROG pin.
MXGS2 in MMSIZ allows CSGP2 to follow either 64K CPU addresses
or 512K expansion addresses.
MXGS1 in MMSIZ allows CSGP1 to follow either 64K CPU addresses
or 512K expansion addresses.
