CS35L32
4.12 Signaling Format
4.12.2 Transmitting Data from a Single-CS35L32 Configuration
For a single CS35L32, the user clears SHARE (see p. 39 ). When transmitting data via the ADSP, the monitor data is
packed as shown in Table 4-9 : left channel VMON[15:0], VPMON[7:0] and right channel IMON[15:0], STATUS.
Signal
Monitoring
,
Section 4.8 .
VMON_OVFL
(VMON overflow) xMON overflow. Indicates the overrange status in the VMON, IMON, or VPMON ADC signal path
0 (Default) No clipping has occurred anywhere in the ADC signal path.
1 Clipping has occurred in the ADC signal path.
The programming of IMON_SCALE may cause IMON_OVFL to be set. See Section 7.20 .
IMON_OVFL
(IMON overflow)
VPMON_OVFL
(VPMON overflow)
VMON
(voltage monitor)
16- or 12-bit representation of the voltage across the load, sensed on VSENSE±
IMON
(current monitor) 16- or 12-bit representation of the voltage sensed across an external 0.1-  resistor in series with the
SPKOUT+ terminal, sensed on ISENSE±
VPMON
(battery voltage) 8-bit representation of the voltage present on VP pin, i.e., the system’s battery voltage, sensed
internally
LED Driver
Section 4.9 .
LED12_FLEV
(LED12 flash event) LED1 or LED2 flash event (Logical OR of LED1_FLEV and LED2_FLEV , see p. 43 )
0 (Default) No driver flash current delivered to either LED1 or LED 2
1 Flash current delivered to LED1, LED2, or both
LED12_MVEV
(LED12 Movie Mode
event) LED1 or LED2 movie event (Logical OR of LED1_MVEN and LED2_MVEV , see p. 43 )
0 (Default) No driver movie current delivered to either LED1 or LED 2
1 Movie current delivered to LED1, LED2, or both
LED_TIMERON
(flash timer) Flag indicating whether the flash timer is On. See Section 7.22 .
0 (Default) LED Flash timer Off
1 LED Flash timer On
Power down PDN_DONE
(power-down done) Indicates whether the CS35L32 is completely powered down and MCLK can be stopped. See
Section 7.20 .
0 Not completely powered down. PDN_DONE = 0 if any blocks still require MCLK
INT
. After
powering down using PDN_ALL or the individual power-down bits, the CS35L32 transitions to a
powered-down state, after which, PDN_DONE is set and MCLK
INT
can be removed.
1 (Default) Powered down
