Product specification
USB smart card reader (OTP or ROM)
TDA8030; TDA8031
8.1.5.7
Power control register
The Power Control Register (PCR) performs two tasks:
1.
Starts or stops card sessions
2.
Reads from or writes to auxiliary card contacts C4 and C8.
Table 26
Power control register (address 07H; read and write); note 1
Note

All bits are cleared after reset.

Contact 8: When writing to the PCR bit C8 will output the value of bit C8. When reading
from the PCR, bit C8 will store the value on pin C8.
Contact 4: When writing to the PCR bit C4 will output the value written of bit C4. When
reading from the PCR bit C4 will store the value on pin C4.
1.8 V cards: if bit 1.8V is set, then V
CC
= 1.8 V.
Reset bit: When the card is activated, pin RST is the copy of the value written in RSTIN.
3 or 5 V cards: If bit 3/5V is set to logic 1, then V
CC
is 3 V; If bit 3/5V is set to logic 0,
then V
CC
is 5 V.
Start: If the microcontroller sets bit START to logic 1, then the selected card is activated;
see Section 8.3.3. If the microcontroller resets START to logic 0, then the card is
deactivated; see Section 8.3.4. START is automatically reset in the event of emergency
deactivation.
For deactivating the card, only bit START should be reset.
