A controller can then transmit the device configuration
over a shorter period.
On reading address 0x7C the byte stored in the EEP-
ROM is output as part of the BiSS device ID. Here,
high-order bits 7:3 are part of the manufacturer’s ID;
low-order bits 2:0 act as an indicator of the timeout op-
tions (regular or short timeout, see Table 43).
