AMENDMENT HISTORY
Description
First issue
1.Modify P85 Internal Hihg RC.
2.ADD Brown-Out reset.
1. Modify Topr value.
2. ADD IHRC curve.
1. Modify Brown-Out Reset description
2. Remove power consumption(Pc)
3. Add T0 RTC description
4. Add Fcpu limitation by Noise filter enable.
5. Modify ELECTRICAL CHARACTERISTIC.
1. The Fcpu of IHRC_16M and IHRC_RTC mode is limited to Fosc/4~Fosc/16.
2. Modify IHRC frequency curve in characteristic graphs section.
1. Add Marking Definition.
2. Modify ELECTRICAL CHARACTERISTIC.
1. Modify RST/P1.1/VPP PIN DISCRIPTION.
2. Modify ELECTRICAL CHARACTERISTIC
1. Modify “Chapter 4.3 OSCM REGISTER” STPHX bit description : external high-speed
oscillator control bit=> High-speed oscillator control bit.
2. Modify “Chapter 9 INSTRUCTION TABLE”: NOP/PUSH/POP/RETI instructions.
3. Modify “Chapter 2.1.2 CODE OPTION TABLE” code option High_Clk = IHRC_RTC
description.
4. Modify “Chapter 2.3.2 STACK REGISTERS” description : 9-bit >> 10-bit data
memory.
5. Update “Table of Content” and the others.
Modify operating temperature 0~70℃ >> -10~70℃.
Add T0 timer limited:
1. T0 timer have T0IRQ clock loss issue in High_Clk code option = “IHRC_RTC” and
“T0TB = 1” mode. So user have to use main routing polling T0C state by the way,
recommend refer to “T0 TIMER WITH RTC FUNCTION OPERATION SEQUENCE”
chapter
2. “T0 TIMER WITH RTC FUNCTION OPERATION SEQUENCE” chapter
description: main routing structure polling T0C value overflow to update RTC time.
Main routing interval time as one cycle is not more than 200ms.
3. Add RTC limited description at “INTERRUPT “chapter.
Modify Hong Kong Office address.
Modify “WATCHDOG TIMER” chapter example program fail.
B0BSET FWDRST >> MOV A, #5AH
B0MOV WDTR,A
Modify “TC0 CLOCK FREQUENCY OUTPUT (BUZZER)” chapter description :
TC0 Setup TC0OUT output from TC0 to TC0OUT (P5.4). The external
high-speed clock is 4MHz.. The TC0OUT frequency is 0.5KHz. Because the
TC0OUT signal is divided by 2, set the TC0 clock to 1KHz. The TC0 clock source
is from external oscillator clock. T0C rate is Fcpu/4. The TC0RATE2~TC0RATE1
= 110. TC0C = TC0R = 131.
>>
TC0 Setup TC0OUT output from TC0 to TC0OUT (P5.4). The external
high-speed clock is 4MHz.. Fcpu = Fosc/4 = 1MIPS. The TC0OUT frequency is
1KHz. Because the TC0OUT signal is divided by 2, set the TC0 clock to 2KHz.
The TC0 clock source is from external oscillator clock. TC0 rate is Fcpu/4. The
TC0RATE2~TC0RATE1 = 110. TC0C = TC0R = 131.
Modify “ELECTRICAL CHARACTERICS” chapter operating temperature from -10~70℃
to -20~85℃ and others.
Delete “T0 TIMER WITH RTC FUNCTION OPERATION SEQUENCE” chapter
1. Modify “ELECTRICAL CHARACTERISTIC” chapter :
I/O output source current (max.) = 20mA.
I/O output source current (min.) = 20mA.
2. Add PIN ASSIGNMENT : SN8P2501BA (MSOP 10pin)
