DESCRIPTION
1) Added Guaranteed By Design notes to the Electrical Specifications.
2) Added explanation on NV properties of RTCA_ADJ[ ] and
PREG/QREG[ ] and corrected entries in Table 54.
3) Added note that transitions to BROWNOUT mode must be avoided
during page erase operations.
4) Added note in Application Section (3.1) stating that filter com-
ponents other that those shown on the Demo Boards should not be
connected to the sensor input pins. Added reference to AN5292.
5) Consolidated spelling of low-power modes (SLEEP, LCD,
BROWNOUT) and of COMPSTAT register.
6) Corrected value for C2 capacitor in Table 68.
7) Extended explanation of WD_OVF (not preserved in SLEEP mode)
and corrected entries in Table 54.
8) Added explanation of WD_NROVF_FLAG.
9) Added explanation on MPU activity on transition to BROWNOUT
mode in section 2.4.2.
1) Throughout document: Added bit ranges to all register fields where
missing (e.g. MPU_DIV[2:0]).
2) Figure 1: Corrected name for PSDI and PSDO signals.
3) Section 1.2.3 (page 11): Added note concerning tailoring CE code
for ADC resolution.
4) Section 1.1.1, Table 5 (page 15): Corrected equations for EQU=3.
Added note – not all CE codes support all equations.
5) Clarified Section 1.3.2 (page 16).
6) Section 1.4 80515 MPU Core:
 (page 19) Table 6: Change approximate frequencies to exact
frequencies.
 (page 19): Changed providing Library to providing demonstration
source code.
 (page 20) Added note about MUX_DIV=0 disables ADC output.
 (page 21) See restrictions on INTBITS register.
 (page 22) Added P1-P3 to Table 10.
 (page 24) Updated Data Pointer description.
 (page 25) Table 14: Added note about clearing the WRPROT_CE
and WRPROT_BT bits. Updated description for FWCOL0,
FWCOL1.
 (page 26) Section 1.4.6: Clarified SOBUF, S1BUF as Tx and Rx
buffers.
 (page 27): Added caution on proper way to clear flag bits.
 (page 31) Table 25: Added Interrupt sources for Ext. Interrupts 2-6.
7) Section 1.5.2 PLL and Internal Clocks
 (page 37) Table 37: Changed frequencies to exact frequencies.
 (page 38): Added caution concerning frequency relationship to
specific CE code.
8) (page 39) Section 1.5.3 Real-Time Clock (RTC): Added description
for observing RTC timing on TMUXOUT pin.
9) (page 46) Section 1.5.7 Digital I/O: Added caution about not sourcing
current in or out of DIO pins. Updated Figure 9.
10) Section 1.5.11 SPI Slave Port, (page 52): Clarified description of
I/O RAM access via the SPI interface. Added Table 48.
11) Section 2.3 Battery Modes (page 57): Added details on software
