ADDITIONAL (Sa) AND INTERNATIONAL (Si) BIT OPERATION
On the receiver, the RAF and RNAF registers always report the data as it is received in the additional (Sa) and
international (Si) bit locations. The RAF and RNAF registers are updated with the setting of the receive align frame
bit in status register 2 (SR2.6). The host can use the SR2.6 bit to know when to read the RAF and RNAF registers.
It has 250
ms to retrieve the data before it is lost.
On the transmitter, data is sampled from the TAF and TNAF registers with the setting of the transmit align frame bit
in status register 2 (SR2.3). The host can use the SR2.3 bit to know when to update the TAF and TNAF registers. It
has 250
ms to update the data or else the old data is retransmitted. Data in the Si bit position is overwritten if either
the framer is programmed (1) to source the Si bits from the TSER pin, (2) in the CRC4 mode, or if the framer (3)
has automatic E-bit insertion enabled. Data in the Sa bit position is overwritten if any of the TCR.3–TCR.7 bits are
set to 1. Please see the TCR register descriptions for more details.
