Software reset. A write operation on this register will reset all internal registers to their default values, and the sta-
Interrupt pin operation mode selection
00H is for the first version.
tus of all ports are set to the default status. The content in this register can not be changed.
Reserved
Reserved. For normal operation, this bit should be set to ‘0’.
This bit selects 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 all the other channels.
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 all channels.
= x0: open drain, active low (with an external pull-up resistor)
= 01: push-pull, active low
= 11: push-pull, active high
