Product specification

PCD5013

8.5.5.3 Receiver warm-up setting packets

(ID = 11H to 15H)

CLS: control line setting (Table 22). This is the value to be

output on the receiver control lines (S0 to S7) for this

receiver warm-up state. Value after reset = 0.

SE: step enable (Table 22). The receiver setting is

enabled when the bit is set. If the bit is cleared then that

step in the receiver warm-up sequence is disabled and all

following steps are ignored. Value after reset = 0.

LBC: low battery check (Table 22). If this bit is set, the

PCD5013 checks the status of the LOBAT port just before

leaving this receiver warm-up state. Value after reset = 0.

ST: step time (Table 22). This sets the duration time for

receiver warm-up until the next receiver state. The setting

is in 625 µs steps and valid values are:

625 µs (ST = 01H) to 79.375 ms (ST = 7FH).

Value after reset = 01H.

s: setting number, see Tables 21 and 22 for the s names

and values and location in the receiver warm-up packet.
