16.1.5 - RTCAH & RTCAL: RTC ALARM Registers
When the programmable counters reach the 32-bit value stored into RTCAH & RTCAL registers, an alarm
is triggered and the interrupt request RTAIR is generated. Those registers are not protected.
RTCAL (EC12h)
RTCAH (EC14h)
Note: Those registers are not reset
16.2 - Programming the RTC
RTC interrupt request signals are connected to Port2, pad 10 (RTCSI) and pad 11 (RTCAI). An alternate
function Port2 is to generate fast interrupts firq[7:0]. To trigger firq[2] and firq[3] the following configuration
has to be set.
EXICON ESFR controls the external interrupt edge selection, RTC interrupt requests are rising edge
active.
EXICON (F1C0h)
Notes: 1. EXI2ES and EXI3ES must be configured as "01b" because RCT interrupt request lines are rising edge active.
EXISEL ESFR enables the Port2 alternate sources. RTC interrupts are alternate sources 2 and 3.
EXISEL (F1DAh)
Notes: 1. Advised configuration.
