0EH: IB Start Register II

15 AUTOSTART3 AUTOSTART3 is used to make Routine 3 an auto starting routine. If this bit is made HIGH, the routine is

auto starting at the point in time indicated by SA/DA3.

14 STDIR3

If STDIR3 is programmed HIGH, execution of Routine 3 is started directly. After execution has finished

this bit is taken LOW by the MU9C8148.

13 START3

If START3 is made HIGH, execution of Routine 3 is started at the point in time indicated by SA/DA3.

START3 is taken LOW by the MU9C8148 after execution has been completed.

12 SA/DA3

If SA/DA3 is made HIGH, execution of Routine 3 takes place directly after the RII has been received. If

SA/DA3 is LOW, execution is started after the second C-bit in the FS field.

11 AUTOSTART4 AUTOSTART4 is used to make Routine 4 an auto starting routine. If AUTOSTART4 is programmed

HIGH, the routine is auto-starting at the point in time indicated by SA/DA4.

10 STDIR4

If STDIR4 is made HIGH, execution of Routine 4 is started directly. After execution has finished STDIR4

is taken LOW by the MU9C8148.

9

START4

If START4 is HIGH, execution of Routine 4 is started at the point in time indicated by SA/DA4. START4

is taken LOW by the MU9C8148 after execution has been completed.

8

SA/DA4

If SA/DA4 is made HIGH, execution of Routine 4 takes place directly after the RII has been received. If

SA/DA4 is LOW, execution is started after the second C-bit in the FS field.

7

AUTOSTART5 AUTOSTART5 is used to make Routine 5 an auto-starting routine. If AUTOSTART5 is set HIGH, the

routine is auto starting at the point in time indicated by SA/DA5.

6

STDIR5

If STDIR5 is made HIGH, execution of Routine 5 is started directly. After execution has finished STDIR5

is taken LOW by the MU9C8148.

5

START5

If START5 is set HIGH, execution of Routine 5 is started at the point in time indicated by SA/DA5.

START5 is taken LOW by the MU9C8148 after execution has been completed.

4

SA/DA5

If SA/DA5 is set HIGH, execution of Routine 5 takes place directly after the RII has been received. If

SA/DA5 is LOW, execution is started after the second C-bit in the FS field.

3

AUTOSTART6 AUTOSTART6 is used to make Routine 6 an auto-starting routine. If AUTOSTART6 is set HIGH, the

routine is auto-starting at the point in time indicated by SA/DA6.

2

STDIR6

If STDIR6 is set HIGH, execution of Routine 6 is started directly. After execution is finished, STDIR6 is

taken LOW by the MU9C8148.

1

START6

If START6 is set HIGH, execution of Routine 6 is started at the point in time indicated by SA/DA6.

START6 is taken LOW by the MU9C8148 after execution has been completed.

0

SA/DA6

If SA/DA6 is set HIGH, execution of Routine 6 takes place directly after the RII has been received. If

SA/DA6 is LOW, execution is started after the second C-bit in the FS field.
