S = Start (1 bit)
SA = Slave Address (7 bits)
SR = SRW bit (1 bit)
M = Slave device send acknowledge bit (1 bit)
D = Data (8 bits)
A = ACK (RXAK bit for transmitter, TXAK for receiver, 1bit)
P = Stop (1 bit)

Note: *When a slave address is matched, the device must be placed in either the transmit mode and then
Write data to the SIMD register, or the receive mode where it must implement a dummy read from the
SIMD register to release the SCL line.

Programming Methodology
The device programming interface should utilise an
adaptor with an integrated 16MHz crystal.

XOSCIN (Pin4) IC system clock
When programming, the device needs to be located
on a Socket with a 16MHz crystal connected between
Pin XOSCIN and ground. Holtek provides an e-link
or e-WriterPro tool for communication with the PC.
Between the e-link and the device there are four
interconnecting lines, namely VDD, VSS, PCLK and
DIN pins.
