The clock frequency register is used only in master mode when the interface
generates the serial clock.
Description
Division factor of 12-MHz reference clock
(2<=CLK_FREQ<= 2047)
In master mode, this register defines the transmission
baud rate from a frequency ratio based on a 12-MHz
reference clock. The transmission clock frequency can
be programmed from 5.8 kHz to 6 MHz in steps or
increments of 83 ns.
Clock frequency = 12 MHz/CLK_FREQ with 2 <=
CLK_FREQ <= 2047.
CLK_FREQ: division factor of 12-MHz reference clock (2<=CLK_FREQ<=
2047)
In master mode, this register defines the transmission baud rate from a
frequency ratio based on a 12-MHz reference clock. The transmission clock
frequency can be programmed from 5.8 kHz to 6 MHz in steps or increments
of 83 ns.
Clock frequency = 12 MHz / CLK_FREQ with 2 <= CLK_FREQ <= 2047.
Description
Overhead clock periods in frame duration
(0 = OVER_CLOCK = 1023)
Description
Mask of frame duration error interrupt (active
at 0)
Mask of transmit interrupt (active at 0)
