ADDRESS NAME SET DESCRIPTION
ROM_ADDR(4:0) USER_BITS(4:0) x Available for reading from a status register
ROM_ADDR5 Reserved x If using 6-wire host protocol, program this bit to 0
ROM_ADDR6 SCLPOL x Determines polarity of HCLK signal
ROM_ADDR7 HOST_PROTOCOL 0 If using 6-wire host protocol, program this bit to 1
ROM_ADDR8 HOST_PORT_EN 1 GPIO(22:16) is on "Host Port" pins
ROM_ADDR9 OCM_START 1 1 = OCM becomes active after OCM_CLK is stable
ROM_ADDR(12:10) USER_BITS(7:5) x Available for reading from a status register
ROM_ADDR13 OSC_SEL 0 0 = XTAL and TCLK pins are connected
ROM_ADDR14 OCM_ROM_CFG(1) 1 1 = All 48K of ROM is in external ROM
