Description
First publication with changes with respect to the preliminary data sheet
(PDS) as follows:
1) Corrected reversed labels for Timer/Counter 1 and 2 in Table 22.
2) Updated Figure 7 (Interrupt structure).
3) Updated range for RTC_A from 1.9 PPM to 3.8 PPM.
4) Changed sleep mode current at 25°C to 0.7 µV and deleted entry
for typical sleep mode current over temperature.
5) Corrected bit enumeration for FLSH_PGADR[7:2].
6) Corrected various typographical errors (TRIMMT etc.).
7) Corrected entries under “Wk.” Column for GP0-GP7 in alphabetical
I/O RAM table.
8) Added explanation for hysteresis at the V1 pin in Applications sec-
tion.
9) Replaced graph showing system performance specification over
temperature with specification on accuracy of VREF compensa-
tion.
10) Changed accuracy of VREF compensation over temperature to
±15 PPM/°C
11) Changed LSB values provided for temperature sensor.
12) Added minimum output level for VLC1 LCD voltage.
13) Removed access to I/O RAM from SPI Port description.
14) Updated numerous parameters in Electrical Specification (tem-
perature sensor, supply current for mission and battery modes).
15) Corrected number of pre-boot cycles in Flash Memory Section.
16) Updated entries in I/O RAM table under “Wake” column.
17) Updated CE register tables.
Changes and corrections:
1) Stated < 0.1% for accuracy for both H and non-H parts over
2000:1 range on title page.
2) Added STOP and IDLE bits in description of PCOM SFR.
3) Consolidated spelling of RTCA_ADJ.
4) Added explanation for Figure 18.
5) Completely revised section 2.5.2 (Wake on Timer).
6) Improved description of hysteresis in Application Section (3.11).
7) Corrected bit range for CE_LCTN to CE_LCTN[7:0].
8) Corrected bit assignment for control of DIO56 – DIO58 (DIO_56[4]
and DIO_DIR56[7].
9) Added LCD_SEG19[ ] to Table 47.
10) Added text in Table 47 stating that registers RTC_SEC to RTC_YR
do not change at reset.
11) Specified Voltage LSB in CE Interface Description (for sag de-
tection).
12) Corrected formulae for RMS calculation below Table 56.
13) Updated package outline drawing.
14) Added text describing connection of a trace emulator to the
71M6534 in section 3.13.
15) Clarified write delay that applies to the RTC_SEC and other RTC
registers in section 1.4.3 and Table 47.
16) Added note describing firmware measures to be applied when
using UART1 in full-duplex mode.
