Low-Power PC Card Controller

Interrupt Structure
Interrupt sources in the CL-PS6700 include card inputs, GPIO pins (PCTL/PDREQ_L), and internal status
signals. All interrupts in the CL-PS6700 are edge triggered. There are five register bits that control each
interrupt, as shwon in
Table 4-1
.
The Interrupt Status register indicates which interrupt inputs have transitioned (rising edge or falling edge)
since they were last cleared (using the Interrupt Clear register). The OR’ing of bits in the Interrupt Status
register (bits not masked by the Mask register) generates an interrupt on either the PIRQ[0]_L or
PIRQ[1]_L output as selected in the Interrupt Output Select register. A bit set to ‘1’ in the Interrupt Output
Select register routes the corresponding interrupt to PIRQ[1]. The Interrupt Input Level register reflects
the current state of the raw interrupt sources (signals directly from the PC Card socket, GPIO pins, and
internal status signals).
