2) After a card is scanned, the MCR interface changes serial data of
the MCR to parallel data. Changed data is written in the FIFO
buffer at every character in order from the start mark to the LRC.
The FIFO buffer has the capacity of 96 bytes, and the number of
characters in a card corresponding to each standard is as follows:
JBA (JIS II type): 72 characters maximum (8 bits a character)
ABA (MEGA MACRO FUNCTION II type second track): 40
characters maximum (5 bits a character)
IATA (JIS I type first track): 79 characters maximum (7 bits a
character)
The 2 FIFOs are prepared independently to 2 channels of inter-
face. These FIFOs can be read simultaneously when connected
to a MCR corresponding to JBA/ABA or IATA/ABA.
3) When a card has been scanned, interrupts for the MCR interface
are activated.
4) The main CPU reads taken card data from the FIFO buffer in the
interrupt handling. The main CPU can read the data using IN
command of 0WAIT.
Even after the LCR which is the last character of a card was read,
10 to 20 characters of "0" remains in the FIFO buffers. So it is
necessary to reset the FIFO before read enabling the next card
after reading the LCR of the last data.
5) This MCR interface does not read the next card until interrupts are
reset by the main CPU.
12-3-8. VFD Interface
The PSC2 has 2 UARTs (8250) as Mega Macro Function.
PSC+80XH is used as the I/O address for this interface. Only TXD
and DTR are outputted as UART signals from the PSC2.
UART3: PSC2+(800-807H)
UART4: PSC2+(808-80FH)
12-3-9. Analog Touch Panel Interface
The PSC2 has a UART (8250) as Mega Macro Function. PSC+81XH
is used as the I/O address for this interface. TXD, RXD, DTR, and
CTS are inputted and outputted as UART signals from the PSC2.
UART5: PSC2+(810-817H)
12-3-10. General Purpose I/O Port
A 6-bit I/O port used for general purposes is configured in the PSC.
