Optional pull up or pull down resistor may be connected to configure internal ROM program
Required external resistor required to select processor boot from internal ROM (pull down) or external
ROM (pull up).
Drives for a short time after reset, then reverts to high impedance

These pins described in
Table 8
are used for used for basic functions such as clocking, reset and infrared
receiver interface. The main system clock can be derived from an external crystal connected between the
XTLCLK_I and XTLCLK_O pins, or can be received from the CD servo chip via the XTLCLK_I pin. The
CS7410 can accommodate a variety of input frequencies, such as 44.1 KHz x 256, x 384, or x 512.

Serial Interface Pins
The CS7410 Serial Interface pins are described in
Table 9
. CS7410 has three dedicated serial ports, each
with different protocols. The 2-wire serial port (SER1) supports industry standard protocols. This port is typ-
ically used for debug, with the CS7410 as the slave. The slave chip select address is programmable, and
defaults to a 7-bit value of 0x1B. A second serial controller (SER2) supports industry standard 3-wire and
4-wire protocols. In master mode, this interface can control a front panel or a small non-volatile memory. In
slave mode, it can operate under control of an external processor, for example, in a combination unit. The
third serial port (SER3) is a 5-wire master device optimized for reading CD subcodes from the servo chip,
and can also be used a general-purpose serial port.
