TI
res
Playback, Capture and timer interrupts may be cleared simultaneously by writing to the Status Register. These interrupts may be
cleared individually by writing a “0” to the corresponding bit. Note that the timer interrupt requires a minimum wait period of 10 s
after the interrupt is set and before TI is recognized. Use TE to clear the timer interrupt immediately.
This register’s initial state after reset is “100x x000.”

Timer Interrupt. This bit indicates that there is an interrupt pending from the timer count registers.
Reserved for future expansion. Always write zero to this bit.
Version Number. Indicates the version of the AD1845.
Reserved for future expansion. Always write zeros to these bits.
Chip ID Number.
Mono Input Attenuation. The least significant bit represents 3.0 dB attenuation. See Figure 11 to determine
the attenuation.
Reserved for future expansion. Always write zeros to these bits.
Mono Output Mute. M_OUT is muted by setting MOM to 1.
