INT_CH[n]=0 indicates that an interrupt was generated by channel [n+1].
00H is for the first version.
Software reset. A write operation on this register will reset all internal registers to their default values, and the status
of all ports are set to the default status. The content in this register can not be changed.
G.772 monitor
= 00/10: Normal
= 01: Receiver 1 monitors the receive path of channel 2
= 11: Receiver 1 monitors the transmit path of channel 2
Reserved.
This bit selects the E1 or T1/J1 operation mode globally.
= 0: E1 mode is selected.
= 1: T1/J1 mode is selected.
Enable broadcasting mode.
= 0: Broadcasting mode disabled
= 1: Broadcasting mode enabled. Writing operation on one channel's register will be copied exactly to the corre-
sponding registers in other channel.
Global interrupt enable
= 0: Interrupt is globally enabled. But for each individual interrupt, it still can be disabled by its corresponding Inter-
rupt mask Bit.
= 1: All the interrupts are disabled for both channels.
Interrupt pin control
= x0: Open drain, active low (with an external pull-up resistor)
= 01: Push-pull, active low
= 11: Push-pull, active high
Reserved.
