1 = Asserts the RST (set RST = 0) to the smart card interface, 0 = De-assert
the RST (set RST = 1) to the smart card interface. Can be used to extend
RST to the smart card. Refer to
operational in all modes and can be used to extend RST during activation or
perform a “Warm Reset” as required. In auto-sequence mode, this bit should
be set = 0 to allow the sequencer to de-assert RST per the
parameters.
In sync mode (see the
set = 1, RST = 1, if set = 0, RST = 0. Rlen has no effect on Reset in sync
mode.
Smart Card I/O. Read is state of I/O signal (Caution, this signal is not
synchronized to the MPU clock). In Bypass mode, write value is state of
signal on I/O. In sync mode, this bit will contain the value of I/O pin on the
latest rising edge of CLK.
Smart Card I/O Direction control Bypass mode or sync mode. 1 = input
(default), 0 = output.
Smart Card C8. When C8 is an output, the value written to this bit will appear
on the C8 line. The value read when C8 is an output is the value stored in
the register. When C8 is an input, the value read is the value on the C8 pin
(Caution, this signal is not synchronized to the MPU clock). When C8 is an
input, the value written will be stored in the register but not presented to the
C8 pin.
Smart Card C4. When C4 is an output, the value written to this bit will appear
on the C4 line. The value read when C4 is an output is the value stored in
the register. When C4 is an input, the value read is the value on the C4 pin
(Caution, this signal is not synchronized to the MPU clock). When C4 is an
input, the value written will be stored in the register but not presented to the
C4 pin.
1 = High, 0 = Low. If CLKOFF is set = 1, the CLK to smart card will be at the
logic level indicated by this bit. If in bypass mode, this bit directly controls the
state of CLK.
0 = CLK is enabled. 1 = CLK is not enabled. When asserted, the CLK will
stop at the level selected by CLKLVL. This bit has no effect if in bypass
mode.
