This register is used to control the FIFO functions of Smart Card interface.
Bit 6, 7: These two bits are used to set the active level for the receiver FIFO interrupt. For example, if
Bit 5 - 3: Reserved.
Bit 2: Setting this bit to a logical 1 resets the TX FIFO counter logic to initial state. This bit will be
Bit 1: Setting this bit to a logical 1 resets the RX FIFO counter logic to initial state. This bit will be
Bit 0: This bit enables FIFO of Smart Card interface. This bit should be set to a logical 1 before other
5.6
The Smart Card Control Register controls and defines the parity bit protocol for asynchronous data
communications.
BIT 7
Smart Card FIFO Control Register (SCFR, write only at "base address + 2")
the interrupt active level is set as 4 bytes, once there are more than 4 data characters in the
receiver FIFO, the interrupt will be activated to notify the CPU to read the data from the FIFO.
