PCD5013

8.5.6.2

Receiver on setting packets (ID = 16H to 19H)

LBC: low battery check (Tables 24 and 25). If this bit is

set, the PCD5013 checks the status of the LOBAT port just

before leaving this receiver sync setting state. Value after

reset = 0.

CLS: control line setting (Tables 24 and 25). This is the

value to be output on the receiver control lines for this

receiver sync setting state. Value after reset = 0.

ST: step time (Table 24). This sets the waiting time, before

expecting good signals at EXTS1 and EXTS0 at the end of

the warm-up sequence, after turning decoding on.

The setting is in steps of 625

µs. Valid values are:

625

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

reset = 01H.

s: setting number, see Tables 23 and 25 for the s names

and values and location in the receiver on setting packet.

Table 23 s names and values

8.5.7

FORCING RECEIVER LINES (ID = 0FH)

This packet (Table 26) enables host control over the

receiver control line (S0 to S7) settings in all modes except

reset. In reset, the receiver control lines are high

impedance.

FRS: force receiver setting (Table 26). Setting a bit causes

the associated CLS bit in this packet to override the

internal receiver control settings on the corresponding

receiver control line. Clearing a bit returns control of the

corresponding receiver control line to the PCD5013. Value

after reset = 0.

CLS: control line setting (Table 26). This bit setting is

applied to the corresponding receiver control line if the

associated FRS bit is set in this packet. Value after

reset = 0.
