Regardless of register protection settings a short time-
out of typically 1.8 µs can be temporarily activated by
writing value 0x07 to address 0x7C (address 124d).
A controller can then transmit the device configuration
over a shorter period.

Code

001...111
Adr 0x7C, Bit 2:0
Function
Regular timeout (configured by TIMO)
Short timeout (equal to TIMO = 1)
The value written to address 0x7C is also transferred
to the EEPROM, provided an EEPROM has been con-
nected up and is available.
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 42).
