Bit Rate and Clock Option Registers
8.3.1
Receive Baud Rate Generator Registers
8.3.1.1
Receive Baud Rate Period Register (RBPR)
This register contains the preload value for the receive baud rate counter. When using an internal
clock option or an n-times external clock, the preload value in conjunction with the receiver clock
source chosen, determines the receive bit rate. If a 1
× external clock is used, a value of 01h must be
loaded in the RBPR.
8.3.1.2
Receive Clock Option Register (RCOR)
This register is used to select the DPLL mode, and the desired clock source for the receive bit rate
generator.
Bit 7
TLVal – Transmit line value
This bit reflects the logical value of the transmit data pin. It is a read-only bit; writing
to this bit has no effect.
Bit 6
Reserved – must be ‘0’.
Bit 5
DPLL enable
1 = DPLL is enabled
0 = DPLL is disabled
Bits 4:3
DPLL mode selects the type of data encoding used.
