PRODUCTION DATA.
When card insertion or removal is detected on the user card interface (see User Card Insertion / Removal Detection) the INT_UC bit (bit[7]) of interrupt status register (Reg 0x41) and the PRESL_UC bit (bit[2]) of User card interface status register (Reg 0x00) are both set to 1 and the INT pin is asserted low. INT_UC is cleared and the INT pin is released when the interrupt status register is read. PRESL_UC is cleared only when the user card interface status register is read.
