FRM_TC[7:0] Terminal Count. When enabled, the link counter will count
from 1 to the terminal count. The terminal count determines
the number of links available for use. The operational links are
link 1 to the link determined by the terminal count. By default,
the count is determined by the option bit, FRM_DS1_CEPTN
(Table 313 on page 246). In an application, where there is a
mix of DS1 and CEPT links or a small number of links, the ter-
minal count may be set by enabling FRM_TC_EN and setting
the terminal count, FRM_TC[7:0].

Note: Minimum terminal count value is 4.

FRM_TPSSE_IM Transmit Path System Synchronization Error Inter-
rupt Mask. A transmit path system synchronization error
interrupt is generated when synchronization is lost
between the receive system interface and the transmit
path line clock. FRM_TPSSE_IM is a global mask for the
interrupt status from each link. The individual link transmit
path system error interrupt status bits,
1
FRM_TPSSEI[28:1] are summarized in FRM_AR_IS bit
14 of FRM_SFGR3 (Table 315 on page 248).
0 = allows any synchronization error, as reported in the
synchronization status registers, to generate an inter-
rupt.
1 = masks any synchronization error, as reported in the
synchronization status registers, from generating an
interrupt.
