Description
normal mode
EXT_CLK test mode
unused
RTC source clock runs
all RTC divider chain flip-flops are asynchronously set to logic 0; the RTC
clock is stopped (CLKOUT at 32.768 kHz is still available)
unused
Power-On Reset (POR) override facility is disabled; set to logic 0 for
normal operation
Power-On Reset (POR) override may be enabled
unused
Description
unused
INT is active when TF is active (subject to the status of TIE)
INT pulses active according to
read: alarm flag inactive
write: alarm flag is cleared
read: alarm flag active
write: alarm flag remains unchanged
read: timer flag inactive
write: timer flag is cleared
read: timer flag active
write: timer flag remains unchanged
alarm interrupt disabled
alarm interrupt enabled
timer interrupt disabled
timer interrupt enabled
must be set to logic 0 during normal operations
Remark: note that if AF and AIE are active then INT will be
permanently active
