Data Sheet
W66910 PCI ISDN S/T-Controller
Publication Release Date:
Feb,2001
Revision 1.0

n application with POTS connection, the peripheral devices such as CODEC, DTMF and SLIC can be directly controlled by
W66910, therefore reduce the IO requirement of microprocessor. The peripheral control function includes timer, interrupt inputs
and programmable IO.
There are two timers implemented in W66910: TIMR1 and TIMR2. TIMR1 is a long period timer whcich can be used to control
the cadence of ring tone. TIMR2 is a short period timer which can be used to generate the 20 Hz ring signal.

There are two interrupt input pins : XINTIN0, XINTIN1. Whenever signal level changes (eith rising or falling), a maskable
interrupt is generated which in turn will make an interrupt request if it is unmasked. The interrupt status bits are ISTA:XINT0,
ISTA:XINT1. The mask bits are IMASK:XINT0, IMASK:XINT1. In addition, the signal level can be read at bits SQR:XIND0,
SQR;XIND1. These pins can be used to monitor SLIC hook state and/or DTMF data valid status.
The IO interface provides 11 pins. The pin data are accessed via XDATA1 and XDATA2 registers. The register data is output on
the pin if its output enable bit is set, the read data reflects the current level of pin.
