Chapter 10 Ports (INPUT, I/O PORT)
10 – 22
OPTION B (D): 1.5 V (3.0 V), With regulator
circuit for LCD bias
OPTION A (C): 1.5 V (3.0 V), Without regulator
circuit for LCD bias
(4) Port C mode registers 0/1 (PCMOD0, PCMOD1)
PCMOD0 and PCMOD1 are 4-bit special function registers (SFRs) used to select the sampling frequency
when ports are used for external interrupt, and to select secondary functions other than external interrupt.
The external interrupt sampling frequency is either 128 Hz or 4 kHz.
At system reset all lthe valid bits in the PCMOD0 and PCMOD1 are initialized to “0”.
Port C secondary functions are indicated in Table 10-3.
