9 Stream Rate Control
9.1 H-Bus Stream Rate Control Registers
9.1.1 H-Bus Rate Registers
The H-bus rate registers control the serial data stream rate of operation for each of the H-bus stream groups,
A—H. The upper nibble controls groups B, D, F, and H. The lower nibble controls groups A, C, E, and G.
Table 71. H-Bus Rate Registers
9.2 L-Bus Stream Rate Control Registers
9.2.1 L-Bus Rate Registers
The L-bus rate registers control the serial data stream rate of operation for each of the L-bus stream groups,
A—H. The upper nibble controls groups B, D, F, and H. The lower nibble controls groups A, C, E, and G. Local
streams have a 16.384 MHz rate option (refer to Section 9.2.2 on page 86).
