FI1 TRUE if INT1 interrupt received. If TRUE, the I1P1,
I1P2 positions are available. It is your responsibility to
clear these flags. (See SI, INT1, INT2, I1P1, I1P2,
I2P1, I2P2.)
FR/WN
FI2 TRUE if INT2 interrupt received. If TRUE, the I2P1,
I2P2 positions are available. It is your responsibility to
clear these flags. (See SI, INT1, INT2, I1P1, I1P2,
I2P1, I2P2.)
FR/WN
FIDX1 TRUE if Encoder 1 Index interrupt received. If TRUE,
the IX1P1, IX1P2 positions are available. It is your
responsibility to clear these flags. (See SI, IDX1,
IDX2, IX1P1, IX1P2, IX2P1, IX2P2.)
FR/WN
FIDX2 TRUE if Encoder 2 Index interrupt received. If TRUE,
the IX2P1, IX2P2 positions are available. It is your
responsibility to clear these flags. (See SI, IDX1,
IDX2, IX1P1, IX1P2, IX2P1, IX2P2.)
FR/WN
I1P1 Position 1 latched by interrupt 1 in user units. V R N
I1P2 Position 2 latched by interrupt 1 in user units. V R N
I2P1 Position 1 latched by interrupt 2 in user units. V R N
I2P2 Position 2 latched by interrupt 2 in user units. V R N
IDX1 TRUE if Encoder 1 Index interrupt is enabled. Inter-
nally set FALSE upon receiving the corresponding
index interrupt. (See FIDX1.)
FR/WN
IDX2 TRUE if Encoder 2 Index interrupt is enabled. Inter-
nally set FALSE upon receiving the corresponding
index interrupt. (See FIDX2.)
FR/WN
INT1
INT2
The value of these variables indicate the enabled sta-
tus of interrupt inputs one and two. The value will be 0
if the interrupt is disabled, 1 if it is enabled in a one-
shot mode, and 2 if enabled in a continuous mode.
When enabled in a one- shot mode, the variable will
be zeroed (interrupt disabled) upon receiving an inter-
rupt. (See SI, FI1, FI2, I1P1, I1P2, I2P1, I2P2.)
byte R/W N
IX1P1 Position 1 latched by Encoder 1 index interrupt. V R N
IX1P2 Position 2 latched by Encoder 1 index interrupt. V R N
IX2P1 Position 1 latched by Encoder 2 index interrupt. V R N
IX2P2 Position 2 latched by Encoder 2 index interrupt. V R N
LP2EN TRUE for latch position (LPOS) from encoder 2.
Note: Power must be cycled or a Hard reset performed
before latched position selection will take effect.
FR/WY
LPOS Hardware latched position in user units. V R N
