Bit 6: PLL Clock Input (PCLKI).
This bit selects the input into to the PLL.
0 = MCLK is used.
1 = RCLK[1:8] is used based on the selection in register CCR.
Bit 5: T1/E1 Clock Enable (TECLKE).
When this bit is set the TECLK output is enabled. If not set TECLK is
disabled and the TECLK output is an RLOS output. TECLK requires PLLE to be set for correct functionality.
Bit 4: Clock A Enable (CLKAE).
When this bit is set the CLKA output is enabled. If not set, CLKA is disabled to tri-
state. CLKA requires PLLE to be set for correct functionality.
Bits 3 and 2: Master Period Select [1:0] (MPS[1:0]).
These bits select the external MCLK frequency for the
DS26303. See Table 5-13 for details.
Bit 1: Frequency Select (FREQS).
In conjunction with MPS[1:0], this bit selects the external MCLK frequency for
the DS26303. If this bit is set, the external master clock can be 1.544MHz or a multiple thereof. If reset, the
external master clock can be 2.048MHz or a multiple thereof. See Table 5-13 for details.
Bit 0: Phase Lock Loop Enable (PLLE).
When this bit is set the phase lock loop is enabled. If reset, MCLK is the
applied input clock.
