1.3.7.4.2 TPS2342 Serial Data: Power Controllers to Tunnel
Channel 00b interrupt-capable data and channel 01b non-interrupt-capable data, as defined in the TPS2342
product data, are shifted into the AMD-8132 tunnel from the TPS2342 over [B,A]_HP_SID using
[B,A]_HP_CLK as the clock. Read commands are multiplexed with write commands into the
AMD-8132 tunnel, toggling between channels 00b and 01b.
See the TPS2342 product data for more information.
1.3.7.4.3 TPS2342 Serial Data: Tunnel to Power Controllers
Serial data is transferred over HP_SOD to the TPS2342 where it is stored using [B,A]_HP_CLK as the clock.
The state of the outputs and control signals does not change until a rising edge of [B,A]_HP_LC for
RESETx_L and the rest of the signals. Since the TPS2342 shares HP_LC for RESET_L and the other signals
to latch, it has internal logic to control using [B,A]_HP_LC to change the state of RESET_L and the other
signals. The SHPC global command controls the TPS2342 internal control logic. For more information refer to
the TPS2342 product data.
The data is shifted whenever there is a need to change the state of these signals, normally as a result of a
command to SHPC[B,A]:14. Regardless of how many slots are actually attached to the bridge, the
AMD-8132 tunnel shifts out four slots worth of data followed by pulses on [B,A]_HP_LC.
1.3.7.4.4 TPS2342 SHPC Interrupts, Events, And Errors
Under the conditions described by SHPC[B,A]:20, the AMD-8132 tunnel may assert [B,A]_PIRQA_L,
PME_L, or indicate a system error on the links.
