This bit selects the time base clock source and is cleared on reset.
This bit is not used and always reads as zero.
The LCLK bit selects the clock for the LCD driver and is cleared on reset.
When TBCLK = 0:
When TBCLK = 1:
This bit selects the remote control carrier duty cycle and is cleared on reset.
These bits select the remote control carrier frequency.
(See
1 = OSC selected for time base clock source
0 = XOSC selected for the time base clock source
1 = XOSC divide by 128 selected for the LCD clock
0 = XOSC divide by 64 selected for the LCD clock
1 = OSC divide by 16,384 selected for the LCD clock
0 = OSC divide by 8192 selected for the LCD clock
1 = 33-67% duty selected if RMC3 = 0
0 = 50-50% duty selected
