1.2 2004/1/9 EN-DS-03-12011
曾正智
p.1 移除 internal RC oscillator
p.2 Pin Assignment
p.2 EXT_CLK 改為 RTCC
p.2 工作電壓下限由 2.5V 改為 2.2V
p.3 weak 改成 wake
p.3 PA0: I/O
IAR; Status register; BSR
p.3 EXT_CLK 改成 RTCC
p.4 PB7~0, PA3~0
p.4 FSR 改為 BSR
p.4 EXT_CLK 改成 RTCC, Option 改為 Select
p.6 LV1~LV2, 低電壓偵測改為 2 段
p.7 統一名稱: configuration, BSR,
direct and indirect
p.9 TM58P10 的指令與操作模式無關.
“lcall” and “lgoto”也適用於 general mode
p.9 EXT_CLK 改成 RTCC
p.11 BSR 內容更改
p.11 MCLR 改為 RESETB, Wake 改為 WDT
p.11 RESERB reset 改為 Input a “low”…..
p.13 修改 Fig 5-8, 內容修改. Address 30~3F 無效.
p.15 External interrupt enable 改成 TMR0
interrupt enable
p.15 External interrupt flag 改成 TMR0
interrupt flag
p.16 新增 Key_Debounce 範例
p.17 EXT_CLK 改成 RTCC
p.18 新增 prescaler from TMR0 to WDT 範例
p.18 新增 prescaler from WDT to TMR0 範例
p.19 Synchronize by ripple cpunter 改為 counter.
p.20 BSR 的初值修改,有 2 個無用的位元,其預設值
跟 microchip 不同.已經新增 BSR 的
application note.
p.21 Select register 只有 6 位元
p.24 工作電壓下限由 2.5V 改為 2.2V
p.24 Operating Temperature 改成 0℃~70℃
p.25 NS 的單位應為 Mhz,下限改為 0.2
p.25 TWDT, TRHT 20~30ms

Bit Symbol
Description
Carry and Borrow bit
ADD instruction
SUB instruction
0C
1: a carry occurred from the MSB 1: no borrow (Note1)
0: no carry
0: a borrow occurred from the MSB
Nibble Carry and Nibble Borrow bit
ADD instruction
SUB instruction
1 DC 1: a carry from the low nibble bits 1: no borrow
of the result occurred
0: a borrow from the low nibble bits
0: no carry
of the result occurred
Zero bit:
2Z
1: the result of a logic operation is zero
0: the result of a logic operation is not zero
Power down flag bit: (Note2)
3 PD
1: after power-on or by the CLRWDT instruction
0: execute SLEEP instruction
Time out flag bit:
4 TO
1: after power-on or by the CLRWDT or SLEEP instruction
0: Occur WDT time-overflow

Figure 5-5 Status Register
Note1: A SUB instruction is executed by adding the 2’s complement of the subtrahend, so
C = 1 represents positive result. The Figure 5-5-1 show the relation between C-bit
and borrow.
