RSLIC & CODEC CHIPSET
LM_OK
UTD_OK
OTMP
RAMP_OK
GK_POL
Applying a read command to this register will clear the interrupt caused by the valid change of the LM_OK, UTD_OK, OTMP, RAMP_OK
or GK_POL bit.
Indicating whether the level metering is finished. Changes of this bit from 0 to 1 generate interrupts (the LM_OK bit has
no mask bit).
LM_OK = 0:
LM_OK = 1:
UTD result indication. Changes of this bit from 0 to 1 generate interrupts (the UTD_OK bit has no mask bit).
UTD_OK = 0:
UTD_OK = 1:
Over temperature detection result. Changes of this bit from 0 to 1 generate interrupts if the mask bit OTMP_M in register
LREG18 is set to 0.
OTMP = 0:
OTMP = 1:
Indicating whether ramp generation is completed. Changes of this bit from 0 to 1 generate interrupts if the mask bit
RAMP_M in register LREG18 is set to 0. When the ramp generator starts a new generation, the RAMP_OK bit will be
reset to 0.
RAMP_OK = 0:
RAMP_OK = 1:
ground-key polarity, indicating the active ground-key threshold (positive or negative). Changes of this bit generate inter-
rupts if the mask bit GKP_M in register LREG18 is set to 0.
GK_POL = 0:
GK_POL = 1:
Level meter result is not ready (default);
Level meter result is ready.
No special tone signal (e.g., fax/modem) is detected (default);
Special tone signal (e.g., fax/modem) is detected
Temperature at the RSLIC is below the limit (default);
Temperature at the RSLIC is above the limit;
Ramp generation is not completed (default);
Ramp generation is completed;
Negative ground-key threshold is active;
Positive ground-key threshold is active (default);
