5.2.4
The commands supported by the programming
executive are described in Section 5.2.5 “SCHECK
Command”
Command”.
5.2.5
The SCHECK command instructs the programming
executive to merely generate a response. This
command is used as a “Sanity Check” to verify if the
programming executive is operational.
Expected Response (2 words):
5.2.6
The READC command instructs the programming
executive to read N or Device ID registers, starting from
the 24-bit address specified by Addr_MSB and
Addr_LS.

When this command is used to read the Device ID
registers, the upper byte in every data word returned by
the programming executive is 00h and the lower byte
contains the Device ID register value.
Expected Response (4 + 3 * (N – 1)/2 words for N odd):
5.2.7
The READD command instructs the programming
executive to read N 16-bit words from data EEPROM
memory, starting from the 24-bit address specified by
Addr_MSB and Addr_LS.

Reading unimplemented memory will
cause the programming executive to
reset. Ensure that only memory locations
present on a particular device are
accessed.
