17.5.3 PCMCIA Interface Enable Register
The PCMCIA interface enable register (PER) acts as a mask for the various sources of a
PCMCIA interrupt. Interrupts caused by bits 16-22 are reported as CBSCHLVL interrupts,
while interrupts caused by bits 24-27 are reported as CBIRQLVL interrupts.
Bits 0–15—Reserved
These bits are reserved and must be set to 0.
CB_EVS1—Card B Enable for Voltage Sense 1
CB_EVS2—Card B Enable for Voltage Sense 2
CB_EWP—Card B Enable for Write-Protect
CB_ECD2—Card B Enable for Card Detect 2
CB_ECD1—Card B Enable for Card Detect 1
PER
NOTE: — = Undefined.
