1011 = bus transaction is defined as 11 LCLK periods

1100 = illegal state

1101 = illegal state

1110 = illegal state

1111 = illegal state

Bit 6 / Local Bus Width (LBW).

0 = 16 bits

1 = 8 bits

Bits 8 to 11 / Local Bus Arbitration Timer Setting (LAT0 to LAT3). These 4 bits determine the total

time the Local Bus will seize the bus when it has been granted in the Arbitration Mode (LARBE = 1).

This period is measured from LHLDA(LBG*) being detected to LBGACK* inactive.
