Preliminary Technical Data
Rev. PrE | Page 142 of 148
UART transmit signal or a low power signal to drive a LED. The
modulation can be enabled or disabled with the MOD38EN bit
in the CFG SFR. The 38 kHz modulation is available on eight
pins, selected by the MOD38[7:0] bits in the Extended Port
Configuration SFR (EPCFG, 0x9F).
