from serial EEPROM
Status parity error.
1: means that STE10/100A detected a parity error.
This bit will be set even if the parity error response
(bit 6 of CR1) is disabled.
Status system error.
1: means that STE10/100A asserted the system
error pin.
Status master abort.
1: means that STE10/100A received a master abort
and has terminated a master transaction.
Status target abort.
1: means that STE10/100A received a target abort
and has terminated a master transaction.
Reserved
Status device select timing. Indicates the timing of
the chip’s assertion of device select.
01: indicates a medium assertion of DEVSEL#.
Status data parity report.
1: when three conditions are met:
a. STE10/100A asserted parity error (PERR#) or it
detected parity error asserted by another device.
b. STE10/100A is operating as a bus master.
c. STE10/100A’s parity error response bit (bit 6 of
CR1) is enabled.
Status fast back-to-back.
Always 1, since STE10/100A has the ability to
accept fast back to back transactions.
