The LED activity signals are valid when a card is inserted, powered, and not in reset. For PC Card-16, the LED activity
signals are pulsed when READY(IREQ) is low. For CardBus cards, the LED activity signals are pulsed if CFRAME,
IRDY, or CREQ are active.

Figure 35. Sample LED Circuit
As indicated, the LED signals are driven for a period of 64 ms by a counter circuit. To avoid the possibility of the LEDs
appearing to be stuck when the PCI clock is stopped, the LED signaling is cut off when the SUSPEND signal is
asserted, when the PCI clock is to be stopped during the clock run protocol, or when in the D2 or D1 power state.
If any additional socket activity occurs during this counter cycle, then the counter is reset and the LED signal remains
driven. If socket activity is frequent (at least once every 64 ms), then the LED signals remain driven.

CardBus Socket Registers
The PCI6515 controller contains all registers for compatibility with the
PCI Local Bus Specification
and the
PC Card
Standard
. These registers, which exist as the CardBus socket registers, are listed in Table 36.

3.5.10 48-MHz Clock Requirements
The PCI6515 controller is designed to use an external 48-MHz clock connected to the CLK_48 terminal to provide
the reference for an internal oscillator circuit. This oscillator in turn drives a PLL circuit that generates the various
clocks required for the Smart Card function (Function 5) of the PCI6515 controller.
The 48-MHz clock must maintain a frequency of 48 MHz
±
0.8% over normal operating conditions. This clock must
maintain a duty cycle of 40% 60%. The PCI6515 controller requires that the 48-MHz clock be running and stable
(a minimum of 10 clock pulses) before a PRST deassertion.
The following are typical specifications for crystals used with the PCI6515 controller in order to achieve the required
frequency accuracy and stability.
Crystal mode of operation: Fundamental
Frequency tolerance @ 25
°
C: Total frequency variation for the complete circuit is
±
100 ppm. A crystal with
±
30 ppm frequency tolerance is recommended for adequate margin.
Frequency stability (over temperature and age): A crystal with
±
30 ppm frequency stability is recommended
for adequate margin.
