3.10 Warm Reset
The 73S8010R automatically asserts a warm reset to the card when instructed through bit 1 of the I
2C
Control register (bit Warm Reset). The warm reset length is automatically defined as 42,000 card clock
cycles. The Warm Reset bit is automatically reset when the card starts answering or when the card is
declared mute.
Figure 11: Warm Reset Operation
3.11 I/O Circuitry and Timing
The states of the I/O, AUX1, and AUX2 pins are low after power-on-reset and they are high when the
activation sequencer enables the I/O reception state. See Section 3.7 Activation Sequence for more
details on when the I/O reception is enabled. The states of the I/OUC, AUX1UC, and AUX2UC are high
after power on reset.
When the control I/O enable bit (bit 7) of the control register is set, the first I/O line on which a falling edge
is detected becomes the input I/O line and the other becomes the output I/O line. When the input I/O line
rising edge is detected, then both I/O lines return to their neutral state. The delay between these signals
is shown in Figure 12.
