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 MCLKINT. 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 MCLKINT can be removed.

1 (Default) Powered down
