Xtal_OSC_Off
27
Power down the internal crystal oscillator when set. This
bit can be set when an external clock source is used. If
there is no external clock source and this bit is set, the
chip will hang.
Clock_Buf_Disable
[12:0]
When set, corresponds to the clock disable for
SMARTCARD_CLK, AIO_CLK, VIO_CLK,
HOSTSLAVE_CLK, ASYNCMAST_CLK, BIOLCC_CLK,
BIOSTORAGE_CLK, BIOXPORT_CLK, SIO_CLK,
ME_CLK, VDSP_CLK, VSPARC_CLK, and
SYRISC_CLK. Clocks should only be disabled when the
associated unit is idle – i.e., no outstanding
Cbus/memory transactions or pending operations.
Clock_Buf_Disable[11] also disables the MIclock, and
MOclock buffer inside AIO. Clock_Buf_Disable[10] also
disables VIN1Clock, VIN2Clock VOUTClock (the PTS
clock is not disabled). This field is reset to 0x0000.
Wake Up Source Register
Memory Space Address: 0xC20004
Note: The Wake Up Source register at control bus address 0xC20004 is
used to enable or disable wake-up events. It is reset to zero.
GPIO[0] WE
3
WakeUp Enable. If set, an interrupt event on GPIO[0] will
wake up DoMiNo; otherwise, it is ignored in power down
state.
0UART WE
2
UART WakeUp Enable. If set, a falling edge on
SIO_UART1_RX will wake up DoMiNo, otherwise it is
ignored in power down state.
IR WE
1
IR WakeUp Enable. If set, a falling edge on SIO_IRRX
will wake up DoMiNo, otherwise it is ignored in power
down state.
