Description
T8_Enable— Disable/enable the T8 counter. (Note: This register bit duplicates
the function of register bit 6 of the CTR3 register).
Disables the T8 counter if bit 6 of the CTR3 register is also 0.
Enables the T8 counter if bit 6 of the CTR3 register is also 0 and has no effect if
the T8 counter is already enabled by bit 6 of the CTR3 register being 1.
SINGLE-PASS/MODULO-N
MODULO-N mode. Counter reloads the initial value when terminal count is
reached.
SINGLE-PASS mode. Counter stops when the terminal count is reached.
Time_Out —This bit is set when the T8 terminal count is reached.
No counter time-out occurred.
Counter time-out occurred.
No effect.
Reset flag to 0. Software must reset this flag before using counter/timers.
T8 _Clock —Select the T8 input clock frequency.These bits are not reset upon
Stop Mode Recovery.
SCLK
SCLK ÷ 2
SCLK ÷ 4
SCLK ÷ 8
Capture_INT_Mask —Disable/enable interrupt when data is captured into either
LO8 or HI8 on a positive or negative edge detection in DEMODULATION mode.
This bit is not reset upon Stop Mode Recovery.
Disable data capture interrupt.
Enable data capture interrupt.
Counter_INT_Mask —Disable/enable T8 time-out interrupt. This bit is not reset
upon Stop Mode Recovery.
Disable time-out interrupt.
Enable time-out interrupt.
P34_Out —Select normal I/O or T8 output function for Port 3, pin 4.
P34 as port output.
T8 output on P34.
