For I2C address [6:0] to JTAG bridge
Host I/F, to determine device address.

User_Bits[5:0] for configuration setting

OP_MODE[1:0]:
00 = Normal op. UART in 186 on system pins.
01 = I2C to JTAG bridge.
10 = JTAG port, 5 wires
11 = External parallel control bus using
ROM Addr/Data

SPI_EN: 0 = parallel ROM I/F. 1 = SPI
serial ROM and Cache control

Initial state of OCM ROM:
0 = internal ROM on, and mapped to top 32K
of OCM and OCM boot will be from internal
ROM codes.

1 = Internal ROM off. The external ROM
mapped to entire upper 512K of OCM address.
OCM boot from external ROM code.

OSC_SEL: 0 = Xtal and internal oscillator.
1 = TTL oscillator (on TCLK pin)
