System overview and block diagram
PFC151 is an IO type, static MTP single-chip microcontroller. It uses the architecture foundation of RISC to make the execution cycle of most instructions single-cycle,
Only a few indirectly addressed instructions require two instruction cycles.
PFC151 built-in 2KW MTP program memory and 128 bytes of data memory.
PFC151 built-in a hardware comparator.
PFC151 provides a 16-bit hardware counter (Timer16) and two 8-bit counters with PWM (Timer2, Timer3).
Program memory (ROM)
The program memory memory of PFC151 is MTP (can be programmed multiple times), which is used to store data (including: data, tables, and interrupt entrances) and the program instructions to be executed. The capacity of the program memory of PFC151 is 2KW, as shown in Table 1.
After reset, the program starts from 0x000 (usually goto FPPA0), and the interrupt entrance is at 0x010.
The MTP memory is used by the system from the address "0x7E0 to 0x7FF", and the address spaces from "0x001 to 0x00F" and "0x011 to 0x7DF" are the user's program spaces.
The last 32 address spaces of the MTP program memory are reserved for system use, such as check codes, serial numbers, etc.
System clock and IHRC frequency calibration
The clock sources of the system clock include EOSC, IHRC, and ILRC, and the hardware block diagram of the clock system of PFC151
Use interrupt for example
Users must reserve sufficient stack memory to save the interrupt vector. One-level interrupt requires two bytes, and two-level interrupt requires four bytes. The following sample program demonstrates how to handle the interrupt. Please note that handling the interrupt and pushaf require four bytes of stack memory.
void FPPA0 (void)
{...
$ INTEN PA0; // INTEN = 1;
; When the PA0 level changes, an interrupt request is generated
INTRQ = 0; // Clear INTRQ
ENGINT // Enable global interrupt
...
DISGINT // Disable global interrupt
...
}
void Interrupt (void) // Interrupt program
{
PUSHAF // Store the ALU and FLAG registers
// If INTEN.PA0 is dynamically turned on and off in the main program, the expression can determine whether INTEN.PA0 is 1.
// For example: If (INTEN.PA0 && INTRQ.PA0) {…}
// If INTEN.PA0 is always in the enabled state, the judgment of INTEN.PA0 can be omitted to speed up the interrupt execution.
If (INTRQ.PA0)
{ // The interrupt program of PA0
INTRQ.PA0 = 0; // Only need to clear the corresponding bit (PA0)
...
}
...
// (X:) INTRQ = 0; // It is not recommended to use INTRQ = 0 only at the end of the interrupt program to clear all at once
// Because it may accidentally clear the interrupt that has just occurred and has not yet been processed
POPAF // Restore the ALU and FLAG registers
All IO pins of
PFC151 have the same structure.
