Data transfer with other types of IC cards (direct convention and inverse convention) are
performed as described in the following.
With the direction convention type IC and the above sample start character, the logic 1 level
corresponds to state Z and the logic 0 level to state A, and transfer is performed in LSB-first order.
The start character data above is H'3B. For the direct convention type, clear the SDIR and SINV
bits in SCMR to 0. According to Smart Card regulations, clear the O/E bit in SMR to 0 to select
even parity mode.
With the inverse convention type, the logic 1 level corresponds to state A and the logic 0 level to
state Z, and transfer is performed in MSB-first order. The start character data for the above is
H'3F. For the inverse convention type, set the SDIR and SINV bits in SCMR to 1. According to
Smart Card regulations, even parity mode is the logic 0 level of the parity bit, and corresponds to
When there is no parity error
When a parity error occurs
