TAS5518 Controls and Status
The TAS5518 provides control and status information from both the I2C registers and device pins.
This section describes some of these controls and status functions. The I2C summary and detailed register
descriptions are contained in sections at the end of this document.
2.1
I2C Status Registers
The TAS5518 has two status registers that provide general device information. These are the General Status
Register 0 (0x01) and the Error Status Register (0x02).
2.1.1 General Status Register (0x01)
Device identification code
Clip indicator – The TAS5518 has a clipping indicator. Writing to the register clears the indicator.
Bank switching is busy
2.1.2 Error Status Register (0x02)
No internal errors (the valid signal is high)
A clock error has occurred – These are sticky bits that are cleared by writing to the register.
LRCLK error – When the number of MCLKs per LRCLK is incorrect
SCLK error – When the number of SCLKS per LRCLK is incorrect
Frame slip – When the number of MCLKs per LRCLK changes by more than 10 MCLK cycles
PLL phase-lock error
This error status register is normally used for system development only.
2.2
TAS5518 Pin Controls
The TAS5518 provide a number of terminal controls to manage the device operation. These controls are:
RESET
PDN
BKND_ERR
HP_SEL
MUTE
2.2.1 Reset (RESET)
The TAS5518 is placed in the reset mode by setting the RESET terminal low or by the power up reset circuitry
when power is applied.
RESET is an asynchronous control signal that restores the TAS5518 to the hard mute state (M). Master
volume is immediately set to full attenuation (there is no ramp down). Reset initiates the device reset without
an MCLK input. As long as the RESET terminal is held low, the device is in the reset state. During reset, all
I2C and serial data bus operations are ignored.
Table 21 shows the device output signals while RESET is active.
