REGISTER DESCRIPTION
I/O Direction Register (DIR)
Addr=00h; Reset Value=00h
Addr=01h; Reset Value=X0h
IO11..0=0 I/O pin 11..0 is an input, data on the I/O input is written in DATAn register bit 11..0.
IO11..0=1 I/O pin 11..0 is an output, data contained in DATAn register bit 11..0 is transferred to the I/O output.
I/O Data Register channel #0 (DATA0)
Addr=02h; Reset Value=00h
Addr=03h; Reset Value=X0h
If bit 4 of CONF register (STA)=0 Dynamic I/O mode:
When CS0 is active D011..0 are transferred to the corresponding I/O pins configured as outputs (see DIR reg-
ister). For the I/O pins configured as inputs the corresponding D011..0 will be written by the values applied to
those pins while CS0 is low.
If bit 4 of CONF register (STA)=1 Static I/O mode:
DS11..0 are transferred to the corresponding I/O pins configured as outputs (see DIR register). For the I/O pins
configured as inputs the corresponding DS11..0 will be written by the values applied to those pins.
