<strong>TMPM330</strong><br />

Configure reception operation of a remote control signal with the Remote Control Signal Receive<br />

Control Registers (RMCRCR1, RMCRCR 2 and RMCRCR3) before reception.<br />

(1) Settings of Noise Cancelling Time<br />

Configure noise cancelling time with the RMCRCR4 bit.<br />

RMC monitors a remote control signal in each rising edge of a sampling clock. If “1” is monitored,<br />

RMC recognizes that the signal was changed to “0” after monitoring cycles of “0”s specified in<br />

RMCNC. If “0” is monitored, RMC recognizes that the signal was changed to “1” after monitoring<br />

cycles of “1”s specified in RMCNC.<br />

The following figure shows how RMC operates according to the noise cancel setting of RMCNC<br />

[3:0] = 0011 (3 cycles). Subsequent to noise cancellation, the signal is changed from “1” to “0” upon<br />

monitoring 3 cycles of “0” s, and the signal is changed from “0” to “1” upon monitoring 3 cycles of “1” s.<br />

RMCNC [3:0] = 0011 (3 cycles)<br />
