Power-On Configuration 1_4
The reset value of this bit matches the TTL voltage level
on the A12 pin on reset. If high, the download speed will
be increased to an SCL of 1250 kHz. This bit is for test
purposes only, and should remain clear for normal
operation.
Download Configuration Select
Chooses between the 2 two-wire serial ports for the initial
download. The reset value of this bit matches the TTL
voltage level on the A11 pin at reset. A value of 0 selects
two-wire serial port 0, a value of 1 selects two-wire serial
port 1.
Download ROM Address
The chip address of the serial ROM to be used in the
power-on download is defined by using pull-downs on the
A8, A9, and A10 pins. (See
