Function

Stop Ping-Pong Request.
The host asserts this bit to suspend ping-pong buffering for this mode code.
The host resets this bit to ask the device to re-enable ping-pong. The device
confirms recognition of ping-pong enable or disable status by writing PPON
bit 3.
Ping-Pong Buffer Enable.
The PPEN bit is initialized by the host to select buffer mode. If this bit is high,
ping-pong buffering is selected. If this bit is low, indexed single buffering is
selected.
After reset, the host initializes this bit to logic 1 to enable ping-pong buffering
for this mode code. The host asserts STOPP bit 3 to ask the device to tempo-
rarily disable ping-pong. Negating the STOPP bit asks the device to re-enable
ping-pong. The device confirms ping-pong enable or disable state changes
by writing the PPON bit.
