Figure 9. Architecture of Input Port RC
Output Port RE
When the MOV RE, R instruction is executed, the data in the RAM will be output to port RE and it
provides a high sink current to drive LEDs.
MFP Output Pin (MFP)
The MFP output pin can output the Timer 1 clock or the modulation frequency; the output of the pin is
determined by mode register 1 (MR1). The configuration of MFP is shown in Figure 9. When bit 2 of
MR1 is reset to "0," the MFP output can deliver a modulation output in any combination of one signal
from among DC, 4096Hz, 2048Hz, and one or more signals from among 128 Hz, 64 Hz, 8 Hz, 4 Hz, 2
Hz, or 1 Hz (when using a 32.768 KHz crystal). The MOV MFP, #I instruction is used to specify the
