The register settings and examples of starting character waveforms are shown below for two smart
cards, one following the direct convention and one the inverse convention.
In the H8/3048 Group, the SINV bit inverts only the data bits D7 to D0. The parity bit is not
inverted, so the O/E bit in SMR must be set to odd parity mode. This applies in both transmitting
and receiving.
Direct convention (SDIR = SINV = O/E = 0)
In the direct convention, state Z corresponds to logic level 1, and state A to logic level 0.
Characters are transmitted and received LSB-first. In the example above the first character data
is H'3B. The parity bit is 1, following the even parity rule designated for smart cards.
Inverse convention (SDIR = SINV = O/E = 1)
In the inverse convention, state A corresponds to the logic level 1, and state Z to the logic level
0. Characters are transmitted and received MSB-first. In the example above the first character
data is H'3F. Following the even parity rule designated for smart cards, the parity bit logic
level is 0, corresponding to state Z.
