3.2.3 0x02—Interrupt Mask Register Low (mask_low_reg)
Independent read/write mask bits for each of the Timer Source Register [timer_source; 0x04] interrupt flags. A
logic one represents the masked condition. A logic zero represents the unmasked condition. All mask bits
behave identically with respect to their corresponding interrupt flags. Setting a mask bit prevents the corre-
sponding interrupt flag from affecting the IRQ output. Clearing a mask allows the interrupt flag to affect IRQ
output. Unmasking an active interrupt flag will immediately cause the IRQ output to go active, if currently inac-
tive. Masking an active interrupt flag will cause IRQ to go inactive, if no other unmasked interrupt flags are set.
