2) After reset: BGS12 has finished the reset action and has not entered the firmware initiali-
zation state.
3) Firmware initialization: The software has taken the control right of hardware, and begins to
initialize the firmware.
At reset state is reached with the rising edge of the EMERG_RST signal - either after a nor-
mal module startup (see Section 3.3.1.1) or after a reset (see Section 3.3.2.2). When BGS12
passes through at reset state and after reset state, the firmware initialization state begins.
The firmware initialization is completed as soon as the ASC0 interface lines CTS0, DSR0 and
RING0 as well as the ASC1 interface line CTS1 have turned high (see Section 3.7 and
Section 3.8). At that time, the module is ready to receive and transmit data.
