Each Receive Signaling Register (RS1 to RS16) reports the incoming signaling from two time slots. The
bits in the Receive Signaling Registers are updated on multiframe boundaries so the user can use the
Receive Multiframe Interrupt in the Receive Status Register 2 (SR2.7) to know when to retrieve the
signaling bits. The user has a full 2ms to retrieve the signaling bits before the data is lost. The RS
registers are updated under all conditions. Their validity should be qualified by checking for
synchronization at the CAS level. In CCS signaling mode, RS1 to RS16 can also be used to extract
signaling information. Via the SR2.7 bit, the user will be informed when the signaling registers have been
loaded with data. The user has 2ms to retrieve the data before it is lost. The signaling data reported in RS1
to RS16 is also available at the RSIG and RSER pins.
A change in the signaling bits from one multiframe to the next causes the RSA1 (SR1.7) and RSA0
(SR1.5) status bits to be set at the same time. The user can enable the
INT pin to toggle low upon
detection of a change in signaling by setting either the IMR1.7 or IMR1.5 bit. Once a signaling change
has been detected, the user has at least 1.75ms to read the data out of the RS1 to RS16 registers before the
data will be lost.
