Standard POCSAG alerts (manual or automatic) are
cancelled by resetting bit D0 in the alert set-up register.
User defined alerts are cancelled by writing a zero to the
alert cadence register. Any ongoing alert is cancelled
when a reset pulse is applied to input RST.
7.43
Standard alert patterns have been defined for each
POCSAG call type, as indicated by the function bits in the
address code-word (see Table 1). The timing of these alert
patterns is shown in Fig.10.

When enabled by SPF programming (SPF byte 3, bit D2)
standard POCSAG alerts will automatically be generated
on outputs ATL, ATH, LED and VIB upon call reception.
The alert pattern matches the call type as indicated by the
function bits in the received address code-word.
The original settings of the alert set-up register will be lost.
Bit D0 is reset after completion of the alert.
