OPA1 I/O status description:

The following table illustrates the OPA1 I/O settings.

A1EN

A1NS

A1PS

IO2(A1N), IO3(A1P), IO4(A1E)

IO2, IO3, IO4 are I/Os

IO2, IO3 are I/Os. A1E is OPA1 output

IO2 is I/O. A1P is OPA1 input, A1E is OPA1 output

IO3 is I/O. A1N is OPA1 input, A1E is OPA1 output

A1N, A1P are OPA1 inputs, A1E is OPA1 output

OPA2 Switch Control

The following diagram and table illustrate the OPA2 switch control setting and the corresponding

connections. Note that some switch control selections will force some switches to be controlled by

hardware automatically.

For example:

· The PGAEN=1 will force S6D, S7D to close and the PGAEN=0 will force S6D, S7D to open.

· When the A2EN=0, these switches, S6D, S7D and S9D, are opened by hardware, then the related

I/O pins can be used as the other functions.

Note:

S1D, S2D and S3D are for HT45F23 only.

Switch priority: S4D > S11D > (S12D, S13D, S14D); if A2PS=1, S11D~S14D will be opened by

hardware.

Switch Priority: S5D > S8D; if A2NS=1, S8D will be opened by hardware.
