The UZI Control registers select between the three available serial communication con-
trollers: I
its own UZI Control register.
This register holds the Low byte of the 16-bit divisor count loaded by the processor for
baud rate generation. The 16-bit clock divisor value is returned by {BRGx_DLR_H,
BRGx_DLR_L}, where x is either 0 or 1 to identify the two available UZI devices. Upon
RESET, the 16-bit BRG divisor value resets to
must be between
proper operation is not guaranteed. Thus the minimum BRG clock divisor ratio is 2.
A write to either the Low or High byte registers for the BRG Divisor Latch causes both
bytes to be loaded into the BRG counter and the count restarted.
Bit 7 of the associated UART Line Control register (UARTx_LCTL) must be set to 1 to
access this register for each UZI device. For more information see

Clear UARTx_LCTL[7] to 0 to disable access of the BRG divisor registers.
