Bit No.
Type
Depending on the operating mode, the registers are configured for T1/J1 or E1. Before setting any other registers, the operating mode should be
According to the access method, the registers can be divided into direct registers and indirect registers.
This bit is valid when T1/J1 operating mode is selected by the TEMODE bit (b0, 020H). It selects the operating mode between T1 and J1.
= 0: T1 mode is selected.
= 1: J1 mode is selected.
These two bits are valid when T1/J1 operating mode is selected by the TEMODE bit (b0, 020H). They select the operating format.
= 00: SF format is selected.
= 01: ESF format is selected.
= 10: T1 DM format is selected. This selection is valid in T1 operating mode only.
= 11: SLC-96 format is selected. This selection is valid in T1 operating mode only.
This bit selects the operating mode.
= 0: E1 mode is selected.
= 1: T1/J1 mode is selected.
