DESCRIPTION
Initial Issued
To add W79E823/822 parts and function description
To remove normal package of part number list
To revise PWM function of W79E823 and W79E822 to 4
PWM output channel
1. To remove block diagram.
2. To add GC call function description.
3. Revise DC characteristics spec.
4. Revise Timer Counter of I2C block diagram.
5. Revise “Release brake of PWM” flow chart.
1. Added note for icp mode.
2. Change SFR name IE1 to EIE due to conflict with IE1
bit name in TCON.3.
3. SFR Reset Value Table: Added PWMCON3,
NVMADDR, NVMDAT & NVMCON. Rename PWMP1
to PWMPH, PWMP0 to PWMPL.
4. Port 2 SFR bit P2.0 and P2.1 descriptions reverse
order.
5. To revise PWM function of W79E823, W79E822 and
W79E821 to 4 PWM output channel.
6. Revise Timer Counter of I2C block diagram.
1. Added SFR reg bit P1M1.2, P1M2.2, P1M1.3,
P1M2.3.
2. Port1 SFR register for bit P0.7~P0.0 description in
reverse order.
3. Removed Port1 output mode reg bit P1M1.5, P1M2.5
4. Revised reg bit ENCLK description
5. Changed the “external reset pin has to be held low for
at least two machine cycles”.(not held high)
6. Changed the “All the bits that generate interrupts can
be set or reset by software”. (not by hardware)
7. Revised Figure 26-30-1: Application Circuit of ICP
8. Revised Figure 21-1: Oscillator
9. Revised Figure 24-2: The ADC Block Diagram
Revise the content of UART mode select table.
(SM0, SM1) is exchanged.
