149 / 346 page ![]() Obsolete Product(s) - Obsolete Product(s) ST10F296E Parallel ports 149/346 Figure 46. Block diagram of pin P4.7 1. When SALSEL = 10, 8-bit segment address lines are selected and P4.7 outputs the address. Any attempt to use the CAN2 on P4.7 is masked. However, by enabling the I2C, the segment function is masked, pin P4.7 is automatically configured as open-drain and used to input and output the SDA alternate function. 2. When CAN parallel mode is selected, CAN2_TxD is remapped on P4.6. This occurs only if CAN1 is also enabled. If CAN1 is disabled, no remapping occurs.
