3.1.5
If bit 4 of CONF register (STA)=0
Dynamic I/O mode:
When CS1 is active D
outputs (see DIR register). For the I/O pins configured as inputs the corresponding D
be written by the values applied to those pins while CS1 is low.
If bit 4 of CONF register (STA)=1
Static I/O mode:
CIO0..3=0 The CS0..3 is a static input, DATA is written in DATA2 register bits 0..3.
CIO0..3=1 The CS0..3 is a static output, DATA is taken from DATA2 register bits 0..3.
Pin-strap value:
I/O Data register channel #2 (DATA2)
Addr=07h; Reset Value=00h
Addr=08h; Reset Value=X0h
If bit 4 of CONF register (STA)=0
Dynamic I/O mode:
When CS2 is active D2
outputs (see DIR register). For the I/O pins configured as inputs the corresponding D11..0
will be written by the values applied to those pins while CS2 is low.
