Slot 1: Status address port:
The status port is used to monitor status for UCB1400
functions including, but not limited to, codec settings and power management.
Audio input frame slot 1’s stream echoes the control register index, for historical
reference, for the data to be returned in slot 2. (Assuming that slots 1 and 2 had been
tagged ‘valid’ by UCB1400 during slot 0.)
Status address port bit assignments are:
Bit(19) Reserved (stuffed with 0s)
Bit(18:12) Control register index (echo of register index for which data is being
returned)
Bit(11:2) SLOTREQ bits: Only bits 11 and 10 (PCM L & R) shall be used by
UCB1400. All unused bits shall be stuffed with 0s.
Bit(1, 0) Reserved (stuffed with 0s)
The first bit (MSB) generated by UCB1400 is always stuffed with a 0. The following
7 bit positions communicate the associated control register address, the next 10 bits
are the SLOTREQ bits, two of which (bits 11 and 10) are used by UCB1400 to
request data using the variable sample rate signaling protocol as defined in the
AC ’97 Component Specification The trailing 2 bit positions are stuffed with 0s by
UCB1400.
Slot 2: Status data port:
The status data port delivers 16-bit control register read
data.
Bit(19:4) Control register read data (stuffed with 0s if tagged ‘invalid’ by UCB1400)
Bit(3:0) Reserved (stuffed with 0s)
If slot 2 is tagged invalid by UCB1400, then the entire slot will be stuffed with 0s by
UCB1400.
Slot 3: PCM record left channel:
Audio input frame slot 3 is the left channel output
of UCB1400’s input MUX, post-ADC. The UCB1400’s ADCs are implemented to
support 20-bit resolution. UCB1400 ships out its ADC output data (MSB first) to fill out
its 20-bit time slot.
Slot 4: PCM record right channel:
Audio input frame slot 4 is the right channel
output of UCB1400’s input MUX, post-ADC. The UCB1400’s ADCs are implemented
to support 20-bit resolution. UCB1400 ships out its ADC output data (MSB first) to fill
out its 20-bit time slot.
Slot 12: GPIO status:
Audio output frame slot 12 is used to carry modem GPIO
input data.
Table 3
shows the definition by AC ’97 Component Specification The
UCB1400 does not make use of slot 12 to report its IO pin status. It only uses the
GPIO_INT as an optional means (when the GIEN bit is set in the Feature CSR1
register) to signify an interrupt event (in addition to pin IRQOUT).
