3.11.3.2 Speaker 1 Outputs
3.11.3.3 Speaker Power Output
The maximum power output of the two speakers is not the same due to the
different configurations between Speaker1, which is only single-ended, and
speaker2, which may be differential. Speaker2, thus provides more power.
The maximum specifications given below are available with the maximum
power output configuration values set by AT command.
Only SPK1P can be used.
If a single-ended solution is used with the speaker2 output, only one of the two
SPK2s must be selected. The result is a maximum output power divided by 2.
