Checking content
The test program reads tracks 1 and 2 of the magnetic card (UKOG-
6718RCZZ) based on the ISO7811/1
∼
5 standard, and displays the
data in ASCII code. There are two kinds of data patterns to be read.
TRACK 1: IATA pattern
76 character 7bit/character (Max. 79 character)
TRACK 2: ABA data pattern
28 character, 5bit/character (Max. 40 character)
To read the card data, the following setting is performed.
•
Mode set
46h is set to PSC2 channel 1 mode set register. (IATA, 6bit)
74h is set to PSC2 channel 2 mode set register. (ABA, 4bit)
•
Start mark set
45h is set to PSC2 channel 1 start mark register.
0Bh is set to PSC2 channel 2 start mark register.
•
Interrupt reset
Dummy data is written to PSC2 channel 2 start mark register.
•
Interrupt mask cancel 01h is written to PSC2 MCR mask
register to cancel mask.
In addition, setting for the PSC2 extension interruption is per-
formed.
When the card is scanned, the obtained data is written to the
FIFO buffer from the start mark to LRC in sequence. Then, the
card data is read by interrupt process.
After reading data, the FIFO buffer is reset.
