This register is used in FP mode (FR01 bit 1 set to 1) and when vertical line replication is enabled. The 4
bit number specifies the number of lines between replicated lines. Double scanned lines are counted. The
state machine starts stretching by using the lower nibble value. If the stretched display does not fit it uses
the next higher value. The process continues until the count is equal to upper nibble value or the display
fits. The lower nibble value must be less than or equal to upper nibble value. Set this register before FR40.

Replication Specifications
Font lines beyond 16 are not replicated.
This register specifies the new text mode vertical stretching (along with FR4A, FR4B, FR4C).
FR49(MSB), FR4A(LSB) and FR4B (MSB), FR4C(LSB) constitute two 16 bit registers. Each of the
16 pairs of bits specify scan line replication as shown above.
FR49: Text Mode Vertical Stretching 0 MSB
FR4A: Text Mode Vertical Stretching 0 LSB
FR4B: Text Mode Vertical Stretching 1 MSB
FR4C: Text Mode Vertical Stretching 1 LSB
