______________________________________________________________________________________
Bits 7 to 0: Timeout Counter Configuration Register
Bits (TOC7 to TOC0). These register bits determine
the counting configuration for the three timeout counter
registers. The available configurations are detailed in
the
Timeout Counter Operation section. These registers
can be written when RIU = 1 before activation and can-
not be written to when RIU = 0.
Bits 7 and 6: Reserved.
Bit 5: Contact 8 (C8). Writes to this register bit are out-
put on the C8 pin of the card interface. Reads of this
register bit reflect the value on the C8 pin.
Bit 4: Contact 4 (C4). Writes to this register bit are out-
put on the C4 pin of the card interface. Reads of this
register bit reflect the value on the C4 pin.
Bit 3: 1.8V Card Select (1V8). If this bit is set to 1, the
VCCx supplied to the card interface is 1.8V. This bit
overrides the 3V/5V bit.
Bit 2: Reset Bit (RSTIN). When a card interface is acti-
vated, the RSTx pin is driven according to the value
contained in this register bit.
Bit 1: 3V/5V Card Select (3V/5V). This bit determines
the VCCx level for the card interface. When this bit is set
to 1, VCCx is defined as 3V. When this bit is cleared to
0, VCCx is defined as 5V. When the 1V8 and 3V/5V bits
are set to 1, priority is given to 1V8.
Bit 0: Start (START). This bit controls software activa-
tion/deactivation of the card interface. When this bit is
written to 1, the activation sequence for the selected
card is performed. When this bit is written to 0, the
deactivation sequence for the selected card is per-
formed. Hardware automatically resets the START bit
for the associated card interface when emergency
deactivation occurs. This bit can be written regardless
of the state of the RIU bit.
Power Control Register (PCR)
R = unrestricted read, W = unrestricted write, -n = value after reset. This register is reset to 0011uuuub on RIU = 0.
Note: The AUX card interface does not have register PCR. C4 and C8 are external ports that are internally pulled up (10k
Ω to VCCx),
writing a 1 to C4, C8 configures the weak pullup. Reads are made of the pin state to a different physical bit. Writing a 0 to C4, C8
configures the pulldown. C4 and C8 bits can be written irrespective of the state of the T/R bit.
