Mixed Voltage Operation
When 5VDET/GPI pin is connected to PCMCIA card slot pin #43 (VS1#) as shown in the figure, the following
should be considered.
(1) Interface Status Register bit7*1 indicate inverted 5VDET/GPI.
(2) Card Detect and Control Register bit2*1 (GPI enable) must be kept “0”.

*1) Refer to page 27 “INTERNAL RESISTERS”
*2) As shown in the above table, the RF5C296 and the RF5C396 allow sharing of a power supply between their VCC_SLOTs and the
PCcard slots, provided that the VCC_CORE should be set to 3.3V.
