First publication.

In Table 1, added the Type column and the Equivalent Circuit references.
In Section 1.4, updated program security description to remove pre-boot
and 32-cycle references.
In Section 1.7.1, changed “Mcount is configured in the MCLKCtl register
must be bound between a value of 1 to 7. The possible crystal or external
clock are shown in Table 12.“ to “Mcount is configured in the MCLKCtl
register must be bound between a value of 1 to 7. The possible crystal or
external clock frequencies for getting MCLK = 96MHz are shown in Table
11.”
In the BRCON description, changed “If BSEL = 1, the baud rate is derived
using timer 1.” to “If BSEL = 0, the baud rate is derived using timer 1.”
In Section 1.7.12, removed the following from the emulator port
description: “The signals of the emulator port have weak pull-ups. Adding
resistor footprints for signals E_RST, E_TCLK and E_RXTX on the PCB is
recommended. If necessary, adding 10KΩ pull-up resistors on E_TCLK
and E_RXTX and a 3KΩ on E_RST will help the emulator operate
normally if a problem arises.”
Added Section 4, Equivalent Circuits.
In Ordering Information, removed the leaded part numbers.
1.2

In Table 1, added more description to the SCL, SDA, PRES, PRESB,
VCC, VPC, SEC, TEST and VDD pins.
In Section 1.3.2, changed “FLSH_ERASE” to “ERASE” and
“FLSH_PGADR” to “PGADDR”. Added “The PGADDR register denotes
the page address for page erase. The page size is 512 (200h) bytes and
there are 128 pages within the flash memory. The PGADDR denotes the
upper seven bits of the flash memory address such that bit 7:1 of the
PGADDR corresponds to bit 15:9 of the flash memory address. Bit 0 of
the PGADDR is not used and is ignored.” In the description of the
PGADDR register, added “Note: the page address is shifted left by one bit
(see detailed description above).”
In Table 3, change “FLSH_PGADR” to “PGADDR”.
In Table 3, changed “FLSHCRL” to “FLSHCTL”.
In Table 3, added “Note: the page address is shifted left by one bit (see
detailed description above).” to the PGADDR description.
In Table 5, moved the TRIMPCtl bit description to FUSECtl and moved the
FUSECtl bit description to TRIMPCtl.
In Table 6, changed “PGADR” to “PGADDR”.
In Table 7, added PGADDR.
In Table 11, removed the Mcount 7 row.
In Section 1.7.13.5, deleted “The ETU clock is held in reset condition until
the activation sequence begins (either by VCCOK = 1 or VCCTMR
timeout) and will go high ½ the ETU period thereafter.”
In Section 1.7.13.5 (number 3), deleted “If CLKOFF/SCLKOFF is high and
SYCKST is set=1(STXCtl, b7=1), Rlen=max will stop the clock at the
selected (CLKLVL or SCLKLVL) level.”
In Section 1.7.13.5, deleted number 9.
