Description
This bit reflects the MODE1 pin setting. Only for test purposes.
This bit reflects the MODE0/DA1 pin setting. Only for test purposes.
This bit reflects the BUS_CONF/DA0 pin setting. Only for test purposes.

DMA Clock On:
0 — Power save mode; the DMA circuit will stop completely to save
power.
1 — Supply clock to the DMA circuit.
V
Clock Always On: Logic 1 indicates that internal clocks are always
running when in the suspend state. Logic 0 switches off the internal
oscillator and PLL when the device goes into suspend mode. The
device will consume less power if this bit is set to logic 0. The clock is
stopped about 2 ms after bit GOSUSP is set and then cleared.
Send Resume: Writing logic 1, followed by logic 0 will generate a 10 ms
upstream resume signal.
Remark: The upstream resume signal is generated 5 ms after this bit is
set to logic 0.
Go Suspend: Writing logic 1, followed by logic 0 will activate suspend
mode.
Soft Reset: Writing logic 1, followed by logic 0 will enable a
software-initiated reset to the ISP1583. A soft reset is similar to a
hardware-initiated reset (using the RESET_N pin).
