Description
The software can read or programming serial EEPROM directly through accesses these bits.
EESEL should be set high before starting the EEPROM read/write.
This chip interrupt signal IRQ will be asserted when this bit is set high.
TC5299J can reload CFGA, CFGB and internal PROM, if this bit is set high. When reload
state is completed, READ will be cleared to low.
Attribute and common memory access will be disable if it is programmed to high.
