STLUX385A
Option bytes
nUBC (UBC user boot code reg. protection)
nUBC: not(UBC) EMC byte protection.
GENCFG (general configuration reg.)
Bit 0:
EN_COLD_CFG enables IC cold configuration through the option byte register
AFR_IOMXP0,P1:
0: default case, the IC multifunction signal configuration is performed by the
miscellaneous registers MSC_IOMXP0 and MSC_IOMXP1 (warm configuration).
1: enables the multifunction signal configuration through the option byte registers
AFR_IOMXP0 and AFR_IOMXP1 (cold configuration).
Bit 1:
COMP1_2 enables the complete backward compatibility with the previous device
implementations. In detail, below features are inhibited:
Multiplexing of I
2
C interface on GPIO[5:4], GPIO[1:0], DIGIN[5:4]
Multiplexing of UART interface on GPIO[5:4]
Port0 and Port2 interrupt mask feature (polling)
DIGIN[5:0] pull-up disabling feature
DALI noise rejection filter
Note:
This bit setting ensures the full device compatibility with the previous device model
(STLUX385).
