SMARTCARD INTERFACE (Cont’d)
SMARTCARD INTERRUPT PENDING REGIS-
TER (CRDIPR)
Read Only
Reset Value: 0000 0000 (00h)
This register indicates the interrupt source. It is
cleared after a read operation.
Bit 7 = TXBEP Transmit buffer empty interrupt
pending.
This bit is set by hardware when a TXBE event oc-
curs and the TXBEM bit is set.
0: No TXBE interrupt pending
1: TXBE interrupt pending
Bit 6 = Reserved.
Bit 5 = IOVF Card Overload Current interrupt
pending.
This bit is set by hardware when a IOVF event oc-
curs and the IOVFM bit is set.
0: No IOVF interrupt pending
1: IOVF interrupt pending
Bit 4 = VCRDP Card Voltage Error interrupt pend-
ing.
This bit is set by hardware when the VCARDOK bit
goes from 1 to 0 while the VCRDM bit is set.
0: No VCRD interrupt pending.
1: VCRD interrupt pending.
Bit 3 = WTP Waiting Timer Overflow interrupt
pending.
This bit is set by hardware when a WTP event oc-
curs and the WTPM bit is set.
0: No WT interrupt pending
1: WT interrupt pending
Bit 2 = TXCP Transmitted character interrupt
pending.
This bit is set by hardware when a character is
transmitted and the TXCM bit is set. It indicates
that the CRDTXB buffer can be loaded with the
next character to be transmitted.
0: No TXC interrupt pending
1: TXC interrupt pending
Bit 1 = RXCP Received character interrupt pend-
ing.
This bit is set by hardware when a character is re-
ceived and the RXCM bit is set. It indicates that the
CRDRXB buffer can be read.
0: No RXC interrupt pending
1: RXC interrupt pending
Bit 0 = PARP Parity Error interrupt pending.
This bit is set by hardware when a PAR event oc-
curs and the PARM bit is set.
0: No PAR interrupt pending
1: PAR interrupt pending
SMARTCARD TRANSMIT BUFFER (CRDTXB)
Read/Write
Reset Value: 0000 0000 (00h)
This register is used to send a byte to the smart-
card.
SMARTCARD RECEIVE BUFFER (CRDRXB)
Read
Reset Value: 0000 0000 (00h)
This register is used to receive a byte from the
smartcard.
