TCSRX is an 8-bit register that selects clearing of the counter and controls interrupt request
signals.
TCSRX is initialized to H'00 upon reset and in standby mode, watch mode, subsleep mode, and
subactive mode. Other timing is described in section 9.6.3, Timer Operation.
Bit 7
Input Capture Flag A (ICFA):
Bit 7 is a status flag that indicates that the FRC value has
been transferred to ICRA by an input capture signal. If BUFEA is set to 1 in TCRX, ICFA
indicates that the FRC value has been transferred to ICRA by an input capture signal and that the
ICRA value before this update has been transferred to ICRC.
This flag is set by hardware and cleared by software. It cannot be set by software.
Bit 7: ICFA
Description
0 Clearing
condition:
After reading ICFA = 1, cleared by writing 0 to ICFA
(initial value)
1 Setting
condition:
Set when the FRC value is transferred to ICRA by an input capture signal
Bit 6
Input Capture Flag B (ICFB):
Bit 6 is a status flag that indicates that the FRC value has
been transferred to ICRB by an input capture signal. If BUFEB is set to 1 in TCRX, ICFB
indicates that the FRC value has been transferred to ICRB by an input capture signal and that the
ICRB value before this update has been transferred to ICRC.
This flag is set by hardware and cleared by software. It cannot be set by software.
Bit 6: ICFB
Description
0 Clearing
condition:
After reading ICFB = 1, cleared by writing 0 to ICFB
(initial value)
1 Setting
condition:
Set when the FRC value is transferred to ICRB by an input capture signal
