Silicon Errata Issues

1. Module: SMBus 2.0 Host Controller

DESCRIPTION

SMBus Master Controller violates Bus Idle Time between STO and STA in Byte mode only. This issue only occurs in a

multi-master environment.

Under firmware control, it is possible to generate a new command on the bus before the Bus Idle time expires, thereby

violating the SMBus Idle time.

END USER IMPLICATIONS

The SMBus Master Controller may generate a START condition too soon. The two consequences of this scenario are

that another master will issue a transaction that will get corrupted, which is handled by the lost arbitration mechanism,

or the MEC170x master will unfairly claim the bus too often.

Work Around

There are two solutions:

a) Use the Network Layer instead of Byte mode. This anomaly does not apply to the SMBus Network Layer

operation.

b) If firmware polls the nBB bit to indicate not busy before asserting the PIN bit and writing the data register,

the SMBus Controller will not violate the Bus Idle time.

2. Module: Crisis Recovery Mode

DESCRIPTION

The Boot ROM turns on the internal pull-up on GPIO045 (PVT_STRAP) pin during initialization, then processes the

eFuse settings and samples the GPIO045 input value. It is supposed to sample the pin after waiting a minimum of 1 ms

to determine if it should abort the standard SPI Flash load process and boot from the Crisis Recovery SPI Flash over

the Private SPI Flash interface. However, the boot code turns on the pull-up, does the eFuse processing and samples

the pin immediately without delay. Depending on the external capacitance, this pin may not have enough time to rise to

a high-level and may be misinterpreted as low and enter crisis recovery mode in error.
