Bits 7 and 6: PLL Clock Input [1:0] (PCLKI[1:0]). These bits select the input into to the PLL.
00: MCLK is used.
01: RCLK1 to 8 is used based on the selection in register
10: RCLK9 to 16 is used based on the selection in register CCR.
11: Reserved.
Bit 5: T1/E1 Clock Enable (TECLKE). When this bit is set the TECLK output is enabled. If not set TECLK will be
disabled and the TECLK output is a LOS 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 will be disabled
and the CLKA output is a LOS output. CLKA requires PLLE to be set for correct functionality.
Bits 3 and 2: Master Period Select [1:0] (MPS[1:0]). These bits MPS[1:0] selects the external MCLK frequency
for the DS26334. See Table 6-15 for details. This register when written to will also controller functionality of
Channels 9 to 16.
Bit 1: Frequency Select (FREQS). In conjunction with MPS[1:0] selects the external MCLK frequency for the
DS26334. If this bit is set the external Master clock can be 1.544MHz or multiple thereof. If not set the external
master clock can be 2.048MHz or multiple thereof. See Table 6-15 for details. This register when written to will also
controller functionality of Channels 9 to 16.
Bit 0: Phase Lock Loop Enable (PLLE). When this bit is set the phase lock loop is enabled. If not set MCLK will
be the applied input clock.
