37.3.13 RTP Pin Control 4 Register (RTPPC4)
This register provides the option to set pins to a logic 1 level without influencing the state of other pins. It
eliminates the read-modify-write operation necessary with the RTPPC3 register. Once the pin is
configured in functional mode (using RTPPC0 register), setting the corresponding bit to 1 in RTPPC4 will
not affect the pin's state. Figure 37-21 and Table 37-22 describe this register.

Table 37-22. RTP Pin Control 4 Register (RTPPC4) Field Descriptions
Bit Field Value Description
31-19 Reserved 0 Reads return 0. Writes have no effect.
18 ENASET Sets the output state of RTPENA pin to logic high. Value in the ENASET bit sets the data output
control register bit to 1 regardless of the current value in the ENAOUT bit .
Read:
0 The pin is configured to output a logic low (0) (output voltage is V
OL
or lower).
1 The pin is configured to output logic high (1) (output voltage is V
OH
or higher).
Write:
0 No effect.
1 Set pin to logic high (1) (output voltage is V
OH
or higher).
17 CLKSET Sets the output state of RTPCLK pin to logic high. Value in the CLKSET bit sets the data output
control register bit to 1 regardless of the current value in the CLKOUT bit.
Read:
0 The pin is configured to output a logic low (0) (output voltage is V
OL
or lower).
1 The pin is configured to output logic high (1) (output voltage is V
OH
or higher).
Write:
0 No effect.
1 Set pin to logic high (1) (output voltage is V
OH
or higher).
16 SYNCSET Sets output state of RTPSYNC pin logic high. Value in the SYNCSET bit sets the data output
control register bit to 1 regardless of the current value in the SYNCOUT bit.
Read:
0 The pin is configured to output a logic low (0) (output voltage is V
OL
or lower).
1 The pin is configured to output logic high (1) (output voltage is V
OH
or higher).
Write:
0 No effect.
1 Set pin to logic high (1) (output voltage is V
OH
or higher).
15-0 DATASET[n] Sets output state of RTPDATA[15:0] pins to logic high. Value in the DATAxSET bit sets the data
output control register bit to 1 regardless of the current value in the DATAxOUT bit. Each bit [n]
represents a single pin.
Read:
0 The pin is configured to output a logic low (0) (output voltage is V
OL
or lower).
1 The pin is configured to output logic high (1) (output voltage is V
OH
or higher).
Write:
0 No effect.
1 Set pin to logic high (1) (output voltage is V
OH
or higher).
