4.7 Alarm Insertion / Detection Pins
The
µ
PD98413 has Alarm Insertion and Alarm Detection Pins.
4.7.1 Alarm Insertion Pins
These are input pins, which input the state signals from external peripheral devices. Each port has 3 pins, and
alarm is inserted in the code form.
Those input pins inputs synchronization with MCLK.

TALMA 0-3
TALMB 0-3
TALMC 0-3
I
Alarm signal input.
The alarm, which it is possible to insertion, is LAIS, PAIS, LRDI, PRDI,
PERDI (Server defect, Connectivity defect, Payload defect) and the
following code corresponds to TALMCx-TALMAx.
000: No Alarm
001: LAIS
010: PAIS
011: LRDI
100: One-bit PRDI mode - PRDI (one-bit PRDI, G1 bit5 : 1)
Enhanced PRDI mode - PERDI Server defect (G1 bit5-7 : 101)
101: PERDI Connectivity defect (G1 bit5-7 : 110)
110: PERDI Payload defect (G1 bit5-7 : 010)
111: Reserved
TALMx 0 corresponds to PORT0, while TALMx 3 corresponds to PORT3.
Example:
TALMA 0 = 1, TALMB 0 = 0, TALMC 0 = 0, then the LAIS alarm is
transmitted to port 0.
4.7.2 Alarm Detection Pins
Each port has 3 pins. These pins output a signal indicating that an internally monitored error state has been
detected. The pins can output an error either singly or in combination. The errors to be indicated are selected by
using the RALMR register. If an event occurs, the corresponding alarm pin goes high.
