SPLIT_400MS_100MS_EN
Distinguishing Between CEPT CRC4 with 400 ms
Timer and 100 ms Timer Enable.
When
SPLIT_400MS_100MS_EN = 0, there is no distinction
between CEPT CRC4 with 100 ms timer and 400 ms
timer. FRM_CRAI_CRCTX (0x80P3B, bit 10),
FRM_CRAI_LTS0MFA (0x80P3B, bit 9), and
FRM_CRAI_8MSEX (0x80P3B, bit 7) apply to any link that
is configured either as CEPT CRC4 with a 400 ms timer or
a 100 ms timer. When SPLIT_400MS_100MS_EN = 1,
FRM_CRAI_CRCTX (0x80P3B, bit 10),
FRM_CRAI_LTS0MFA (0x80P3B, bit 9), and
FRM_CRAI_8MSEX (0x80P3B bit, 7) apply only to links
that are configured as CEPT CRC4 witha 400 ms timer.
Links configured as CEPT CRC4 with a 100 ms timer are
determined by the configuration in bits
FRM_CRAI_CRCTX_100 ms (0x80P21, bit 10),
FRM_CRAI_LTS0MFA_100 ms (0x80P21, bit 9), and
FRM_CRAI_8MSEX_100 ms (0x80P21, bit 7).
