**PGMEN** Program Enable - Enable programing of the internal firmware eeprom. Should be reset immediately after writing to the device.
**ECE** External Clock Enable - This bit enables the the external clock input to the SPI controller. In the *AppleIISd*, this effectively switches the SPI clock between 500kHz (ECE = 0) and 3.5MHz (ECE = 1).
**FRX** Fast Receive mode - When set to 1, fast receive mode triggers shifting upon reading or writing the SPI Data register. When set to 0, shifting is only triggered by writing the SPI data register.
