ST7LITE49M
Input capture register high (ATICRH)
Reset value: 0000 0000 (00h)
Bits 15:12 = Reserved.
Input capture register low (ATICRL)
Reset value: 0000 0000 (00h)
Bits 11:0 = ICR[11:0] Input capture data.
Break enable register (BREAKEN)
Reset value: 0000 0011 (03h)
Bits 7:2 = Reserved, must be kept cleared.
Bit 1 = BREN2 Break enable for counter 2 bit
Bit 0 = BREN1 Break enable for counter 1 bit
ICR7
This is a 12-bit register which is readable by software and cleared by hardware after a
reset. The ATICR register contains captured the value of the 12-bit CNTR1 register
when a rising or falling edge occurs on the ATIC or LTIC pin (depending on ICS).
Capture will only be performed when the ICF flag is cleared.
This bit is read/write by software. It enables the break functionality for Counter2 if BA bit
is set in BREAKCR. It controls PWM2/3 if ENCNTR2 bit is set.
0: No Break applied for CNTR2
1: Break applied for CNTR2
This bit is read/write by software. It enables the break functionality for Counter1. If BA
bit is set, it controls PWM0/1 by default, and controls PWM2/3 also if ENCNTR2 bit is
reset.
0: No Break applied for CNTR1
1: Break applied for CNTR1
