Table 90 Audio Interface Conﬁguration Register

Note

1. RSTx = 0 means reset condition if either RSTO or RSTC is asserted; ‘

−’ denotes not affected from reset line.

During reset (RST, RSTO, RSTC) only those registers with an explicitly given reset value are affected. All other

registers are undefined and have to be set by the controller.

Table 91 IOM®-2 Interface Interrupt Flag Register

Notes

1. RSTx = 0 means reset condition if either RSTO or RSTC is asserted; ‘

−’ denotes not affected from reset line.

During reset (RST, RSTO, RSTC) only those registers with an explicitly given reset value are affected. All other

registers are undefined and have to be set by the controller.

2. These flags change from ‘0’ to ‘1’ after the IOM®-2 interface was enabled with CLOCK_MODE = 0 and

MASTERx_EN = ‘0’ after the state machined of the monitor/CI master units are in an initial state.
